In this episode of The Tim Ferriss Show, Tim Ferriss explores the cultural significance of numbers across China, Japan, and Korea, examining how superstitions shape consumer behavior, commercial decisions, and design choices. He traces the origins of number symbolism, particularly the lucky eight and unlucky four, explaining how phonetic similarities to words like "prosperity" and "death" have created powerful associations that influence everything from real estate prices to license plate auctions.
Ferriss reveals how these beliefs extend into luxury hospitality and casino design, where feng shui consultants assess architectural plans and VIP gaming rooms are customized according to gamblers' zodiac signs. The episode also covers regional variations in number symbolism, from Japan's association of eight with expansion to Korea's fortune-telling practices, and examines how traditional number superstitions have adapted to modern contexts, including digital communication and Western cultural misconceptions about number symbolism.

In East Asia, the number eight is widely considered lucky due to its phonetic similarity to words related to wealth and prosperity in Mandarin. The common Chinese New Year greeting "gong xi fa cai" wishes for wealth, with the word for prosperity, "fa," closely resembling the sound of eight ("ba"). In Cantonese, this phonetic resemblance is even more pronounced, strengthening the cultural link between eight and visions of wealth. As a result, eights are highly sought after in phone numbers, addresses, and license plates.
Conversely, the number four is considered unlucky because in Mandarin, four is "sì" (fourth tone) and "to die" is "sǐ" (third tone). While the tones differ, the similarity creates a strong cultural connection between four and death. Buildings across East Asia often skip the fourth floor, similar to how Western architecture may omit the thirteenth floor, and people avoid the number in phone numbers and license plates.
The symbolism of eight as a signifier of wealth reached new prominence during Hong Kong's economic boom in the 1980s. The commercial success and global influence of Hong Kong helped amplify these number superstitions throughout East Asia, becoming an enduring aspect of commercial and social culture.
Numbers perceived as lucky drive economic premiums and influence consumer decisions in several Asian markets. In 2003, Sichuan Airlines paid 2.33 million yuan (about $280,000 USD) for the phone number 8888 8888. In February 2025, a Hong Kong government auction saw the registration mark "8" sell for 11.4 million Hong Kong dollars (about $1.5 million USD).
Market studies reinforce the economic influence of lucky numbers. Economists reviewing apartment sales in Chengdu from 2004 to 2006 found that apartments on floors ending in eight resold at an average premium of 7% and sold about a week faster than units with other floor numbers. Buyers who had more eights in their phone numbers were disproportionately more likely to purchase apartments on floors ending in eight, demonstrating that number superstition directly influences purchasing behavior.
Number symbolism takes on distinct cultural meanings across East Asia. In Japan, the character for eight resembles two strokes spreading apart, symbolizing expansion and linking to the word "suehirogari," meaning "expanding toward the future." The car company originally named "Toyoda" changed its name to "Toyota" because written in katakana, "Toyota" consists of eight strokes, benefiting from the lucky symbolism.
In Korea, the number eight is "pal" in Sino-Korean, but unlike Chinese, it lacks phonetic connections to prosperity. Instead, eight is significant in Korean fortune-telling through "saju-pal-ja," meaning "four pillars, eight characters," referring to a person's birth chart believed to map out their destiny. Korea shares the Chinese aversion to the number four, with elevators sometimes using "F" instead of "4" for the fourth floor.
China's attachment to the auspicious eight was showcased during the Beijing Olympics, with the opening ceremony deliberately scheduled for 8 P.M. on August 8, 2008. On that day, Beijing registered 15,646 marriages, as couples aligned important life events with this extraordinarily lucky date.
Superstition heavily influences luxury hospitality and casino design. In 2004, Sands Macau replaced the iconic slot machine symbol 777 with 888, aligning with the Chinese cultural view of eight as auspicious. Executives have described sending 3D architectural models to feng shui masters in Hong Kong for energy assessment, making feng shui consultants key stakeholders in casino development. Sands Macau modified a corner of its building to ensure the flow of beneficial "qi" from the northeast according to feng shui principles.
The most privileged gamblers experience bespoke environments tailored to maximize their luck. Architect Paul Herotakis described designing a private gaming room at the Venetian in 2012 for a high roller, leveraging the gambler's birthday and zodiac sign with input from a feng shui expert. Caesar's VIP villas feature room numbers starting with eight and skip floors labeled 40 through 49, avoiding the unlucky number four.
Superstition's influence extends beyond casino walls. In 2015, the U.S. Bureau of Engraving and Printing issued a limited run of uncut sheets of eight $2 bills with serial numbers beginning with 8888, sold for $58.88 and limited to 16,888 sheets, targeting collectors who value the number eight's lucky associations.
Tim Ferriss explains that in Western tradition, 666 is viewed as a sign of evil or the number of the beast, originating from the Book of Revelation. However, Ferriss points out that in Chinese culture, 666 can represent good luck. The phrase "liu liu ta shun" wishes smooth sailing or good fortune, and people may receive red envelopes containing money in amounts with sixes during Chinese New Year.
Ferriss also addresses the misconception that the heavy metal hand signal forms three sixes symbolizing 666, clarifying that the gesture, known as the "mano cornuta," is an ancient Mediterranean symbol used for protection against the evil eye. Ronnie James Dio popularized it in heavy metal after borrowing it from his Italian grandmother.
In Chinese internet shorthand, Ferriss notes, the numbers eight eight ("ba ba") sound like "bye bye," making them a common homophonic sign-off. This adaptation of number-sound associations in digital communication highlights how traditional beliefs about numbers are extended and transformed by technology, blending traditional symbolism with contemporary practice.
1-Page Summary
In East Asia, the number eight is widely considered lucky because of its phonetic similarity to words related to wealth and prosperity in Mandarin. The common Chinese New Year greeting, "gong xi fa cai," wishes for wealth, with the word for prosperity, "fa," closely resembling the sound of eight ("ba") in Mandarin.
The phrase "gong xi fa cai" is emblematic of how the "fa" sound for prosperity deepens this association. The number eight and the term for prosperity are viewed as linked; thus, the presence of eights in phone numbers, addresses, and license plates is highly sought after.
In Cantonese, the phonetic resemblance between "eight" and "prosperity" is even more pronounced than in Mandarin, strengthening the cultural and symbolic link between the number eight and visions of wealth especially in Cantonese-speaking communities.
The number four is considered unlucky in East Asia because in Mandarin, four is "sì" (fourth tone) and "to die" is "sǐ" (third tone). While the tones differ, the consonant and vowel are the same, making the words nearly indistinguishable to non-native speakers. This tonal similarity embeds a cultural connection between four and death, leading to strong negative feelings toward the number.
Due to this association, buildings across East Asia often skip the fourth floor or any number containing four, in a manner reminiscent of how Western architecture may omit the thirteenth floor. This practice extends beyond China and is also found in places like Vietnam.
The taboo against the number four influences more than just building floors. People in East Asia frequently avoid the number in phone numbers, license plates, and room numbers ...
Origins of Number Superstitions in East Asia
Numbers perceived as lucky, especially the number eight, drive economic premiums and influence consumer decisions in several Asian markets. The appeal lies in cultural associations with good fortune, prosperity, and memorability.
Businesses and individuals are willing to pay significant premiums for auspicious numbers. In 2003, Sichuan Airlines paid 2.33 million yuan (about $280,000 USD at the time) for the phone number 8888 8888. The phone number, filled with eights, is not only easy for customers to remember but also culturally associated with luck and prosperity. The publicity and perceived good fortune tied to acquiring such a number provides further intangible benefits.
Similarly, the economic value of the number eight extends to vehicle registration. In February 2025, a Hong Kong government auction saw the registration mark "8" sell for 11.4 million Hong Kong dollars (about $1.5 million USD). Both examples show that memorable and prosperous number sequences command high valuations due to their perceived ability to bring good luck and to attract attention.
Market studies reinforce the economic influence of lucky numbers. Economists reviewing apartment sales in Chengdu from 2004 to 2006 found that apartments located on floors ending in eight resold at an average premium o ...

Number symbolism, especially surrounding the number eight, takes on distinct cultural meanings across East Asia, shaped by language, tradition, and context.
Japan adopted Chinese numerals centuries ago, using them in what is called kanji (Chinese: hanzu). The character for eight is visually the same in both languages, but pronounced "hachi" in Japanese. While multiple readings exist, hachi carries visual symbolism in Japan distinct from Chinese tradition. If one visualizes the Japanese character for eight, it resembles an inverted V, much like a capital 'A' without the crossbar. If the apex is slightly separated, it looks like two strokes spreading apart towards the base, symbolizing expansion.
This widening is linked to the Japanese word "suehirogari," meaning "expanding toward the future." Originally used to describe the geometry of a folding fan, which widens out as it opens, suehirogari communicates auspicious growth and prosperity. This visual and conceptual motif of widening prosperity ties the number eight to luck and a bright future in Japanese culture.
Japanese companies have also embedded this symbolism into branding. The car company originally named "Toyoda" changed its name to "Toyota." Written in katakana, "Toyota" consists of eight strokes, whereas "Toyoda" does not. The choice highlighted the association of eight strokes with wealth and good fortune, letting the company benefit from the lucky symbolism tied to the number eight.
Korea, too, uses a number system derived from Chinese. In the Sino-Korean set, the number eight is "pal" (팔). However, unlike Chinese, where the sound of eight is similar to words for prosperity and wealth, "pal" in Korean lacks such a phonetic connection.
Instead, the number eight is significant in Korean fate and fortune telling. One major system, "saju-pal-ja," is built on a person's birth chart. "Saju-pal-ja" translates to "four pillars, eight characters," referring to the year, month, day, and hour of birth, each expressed using two Chinese characters, totaling eight. These eight characters are believed to map out a person’s destiny. In daily Korean usage, "pal-ja" comes to mean your ultimate fate or lot in life, making eight a symbol tied ...
Geographic Variations in Number Symbolism in China, Japan, Korea
Superstition heavily influences luxury hospitality and casino design, weaving ancient beliefs into business decisions and guest experiences, from architecture to room numbers and even limited-edition currency.
Casinos actively use feng shui principles and superstitious associations with numbers to attract luck and promote prosperity. In 2004, Sands Macau replaced the iconic slot machine symbol 777—long popular in Western gaming—with 888, aligning the casino with the Chinese cultural view of eight as an especially auspicious number. Such changes demonstrate how deeply Asian lucky number associations shape casino environments.
Executives at Sands, like William Widener, have described a rigorous design process in which 3D architectural models are created, recorded on DVDs, and sent to feng shui masters in Kowloon, Hong Kong, for energy assessment. This high-tech-meets-tradition approach ensures the space channels positive forces, according to traditional beliefs. As a result, feng shui consultants have become key stakeholders in the casino development process, with their stamp of approval crucial for the design and placement of gaming floors.
Physical alterations to casino buildings are frequently justified according to feng shui logic. For example, Sands Macau modified a corner of its building to ensure the flow of beneficial “qi” from the northeast was not deflected or trapped—a decision driven as much by feng shui as by architecture. Transforming such beliefs into business strategy, casino developers treat these design tweaks as investments in good fortune, aiming to guide luck and financial prosperity directly into their establishments.
The most privileged gamblers experience bespoke environments tailored to maximize their comfort and improve their luck. Architect Paul Herotakis described designing a private gaming room at the Venetian in 2012 for an unnamed high roller. The design leveraged the gambler’s birthday and zodiac sign, with input from a feng shui expert, to create a space believed to be especially lucky for the client.
Similarly, Caesar’s VIP villas feature room numbers starting with eight and skip floors labeled 40 through 49—deliberately avoiding the number four, which is viewed as unlucky due to its phonetic similar ...
Superstition in Luxury Hospitality and Casino Design
Tim Ferriss explains that in Western tradition, 666 is widely viewed as a sign of evil or the number of the beast, originating from the Book of Revelation, chapter 13, verse 18. The verse challenges the reader to calculate the number of the beast, declaring it as a number for a person and specifically identifying it as 666. As a result, 666 generally has a negative connotation and is associated with bad fortune in Western cultures.
Ferriss points out that this view is not universal. In Chinese culture, 666 can actually represent good luck. The phrase "liu liu ta shun" is often used to wish smooth sailing or good fortune, playing on the similar sound of "liu" for six, which can also mean smooth or road. During Chinese New Year, people may receive red envelopes, or "hong bao," containing money in amounts with sixes, such as 600 or 666, symbolizing best wishes and a prosperous path ahead.
Ferriss also addresses the misconception that the popular heavy metal hand signal—pinky and index finger extended, middle and ring finger bent toward the palm, and the thumb wrapped over—forms three sixes, symbolizing 666. He clarifies this is not true. The gesture, known as the "mano cornuta" or horn hand, is an ancient Mediterranean symbol used for protection against the evil eye and bad luck. Ronnie James Dio, who became Black Sabbath’s vocalist in 1979, popularized the gesture in heavy metal after borrowing it from his superstitious Italian grandmother, who used it to ward off negative energy.
Ferriss notes that in Chinese internet sho ...
