Antonio Chi Su was a businessman and restaurateur best known for his long relationship with Mexican actress, dancer, and vedette Lyn May. While Lyn May became a familiar face in Mexican entertainment, Antonio lived a much quieter life and focused primarily on business. He became known to a wider audience because of his marriage to Lyn May and his involvement in the restaurant industry in Mexico City.
Information about Antonio Chi Su is limited compared with that of his famous wife. Many websites publish details about his birth, family, career, and wealth, but some of those details conflict with one another. The most reliable information concerns his restaurant career, his relationship with Lyn May, their marriage, his illness, and his death in 2008.
Who Was Antonio Chi Su?
Antonio Chi Su was a businessman and restaurant owner who lived and worked in Mexico. He became publicly recognized mainly through his relationship with Lyn May, a major figure in Mexican cabaret, film, television, and popular entertainment. Antonio himself was not primarily an entertainer and did not have a major career in acting or television.
He sometimes appears with different spellings, including Antonio Chi-Xuo and Antonio Chi Xuo. These variations have contributed to confusion in online searches, but they generally refer to the same person. He is commonly described as having Chinese heritage, although specific details about his birthplace, nationality, and family origins are not consistently documented.
Antonio Chi Su’s Early Life
Very little verified information exists about Antonio Chi Su’s childhood and early years. Some internet biographies provide exact birth dates, locations, parents, and educational information, but these details are often repeated without clear evidence. Because Antonio was a private businessman, his early life was never documented as extensively as the lives of major entertainers.
His Chinese heritage is frequently mentioned in descriptions of his life. He eventually became established in Mexico and developed a career in the restaurant business. His professional path placed him within the Chinese-Mexican business community in Mexico City, an environment with a long history of Chinese restaurants and family-owned businesses.
Antonio Chi Su’s Restaurant Career
Antonio Chi Su was primarily known as a restaurateur and businessman. His professional activities were connected to Chinese food and restaurant operations in Mexico City. This business career was an important part of his identity long before he became widely associated with Lyn May.
Some accounts connect Antonio with a restaurant known as Siete Mares, while other descriptions use different indentity when discussing his restaurant activities. Because details about the ownership and management of these businesses vary between sources, it is best not to assume that every restaurant mentioned online was entirely owned by Antonio. What is clear is that the restaurant industry played a central role in his working life.
How Antonio Chi Su Met Lyn May
Antonio Chi Su reportedly met Lyn May around 1980. The story commonly told about their meeting connects it to his restaurant business. Lyn May was involved in a film production at the time, and people connected with the production reportedly visited Antonio’s restaurant. This encounter eventually developed into a personal relationship.
The relationship lasted for many years before the couple married. Different accounts give slightly different timelines, but the general story remains consistent: Antonio and Lyn May met around the beginning of the 1980s, developed a long-term relationship, and eventually married toward the end of that decade.
Antonio Chi Su and Lyn May’s Marriage
Antonio Chi Su and Lyn May married in the late 1980s, with 1988 frequently given as the wedding year. Their marriage lasted until Antonio’s death in 2008. During this period, Lyn May continued to work in entertainment, while Antonio remained connected to his business activities.
Their marriage attracted attention because the couple represented two very different sides of public life. Lyn May was a highly visible entertainer who regularly appeared on stage and screen, whereas Antonio preferred to operate away from the entertainment spotlight. Despite the difference in their careers, they remained together for many years.
Antonio Chi Su’s Family Life
Public information about Antonio Chi Su’s immediate family is limited. Much of the available family information comes through Lyn May’s biography rather than through independent records about Antonio. Lyn May has spoken publicly about her children from relationships outside her marriage to Antonio.
There is no strong evidence establishing that Antonio and Lyn May had biological children together. Some online informations describe family relationships in ways that can be confusing, particularly when stepchildren and children from earlier relationships are discussed together. For this reason, claims about Antonio’s exact number of children should be treated cautiously.
Antonio Chi Su’s Illness
Antonio Chi Su was diagnosed with prostate cancer in 2004. He reportedly lived with the disease for several years before his death. His illness occurred during the later part of his long relationship with Lyn May and became an important part of the couple’s final years together.
Lyn May has discussed the emotional difficulty of losing Antonio. His death in 2008 was a major personal loss for her, and she later spoke about her grief in interviews. Some of the stories surrounding the period after his death received considerable attention in the media, but they should not overshadow the broader story of their long relationship.
Antonio Chi Su’s Death
Antonio Chi Su died in 2008 after battling prostate cancer. He was reportedly surrounded by people close to him during the final stage of his illness. His death brought an end to a relationship with Lyn May that had lasted for decades.
After his death, public interest in Antonio increased because of Lyn May’s statements about their relationship and her grieving process. His passing also led to renewed interest in his restaurant career and his connection to one of Mexico’s most famous entertainment personalities.
Antonio Chi Su’s Net Worth
There is no reliable public record establishing Antonio Chi Su’s exact net worth. Various websites have published different estimates, but most do not provide sufficient financial evidence to confirm their figures. Business ownership, property, investments, savings, debts, and other financial factors would all be needed to calculate a person’s true net worth.
Antonio’s restaurant career suggests that he was an established businessman, but the revenue of a restaurant should not be confused with the owner’s personal wealth. A restaurant has expenses such as rent, employees, food, utilities, taxes, and other operating costs. Without detailed financial information, claims about Antonio Chi Su’s exact fortune should therefore be treated as estimates.
Was Antonio Chi Su Chinese?
Antonio Chi Su is frequently described as Chinese or Mexican-Chinese. His and restaurant career are commonly associated with Chinese heritage, and he became part of the Chinese-Mexican community in Mexico City.
However, his exact birthplace and citizenship are not consistently documented. Some online sources describe him as having been born in China, while others suggest that he was born in Mexico to a Chinese family. Without stronger evidence, the safest description is that Antonio had Chinese heritage and built his adult life and business career in Mexico.
Antonio Chi Su’s Connection to Mexico City
Mexico City was central to Antonio Chi Su’s adult life. His restaurant activities connected him to one of the city’s most recognizable Chinese-Mexican commercial areas. Chinese restaurants have been part of Mexico City’s cultural landscape for generations, especially around the historic Chinatown district.
His relationship with Lyn May added another layer of public interest to his business life. Because Lyn was a major entertainment personality, places connected with the couple naturally attracted attention from fans and members of the media. Antonio’s story therefore sits at the intersection of business, Mexican popular culture, and Chinese-Mexican heritage.

Antonio Chi Su’s legacy is largely connected to his business career and his relationship with Lyn May. He did not seek celebrity status in the same way his wife did, but his connection with her ensured that he remained part of Mexican entertainment history.
For Lyn May, Antonio was an important figure in her personal life for many years. His death was deeply significant to her, and she has continued to discuss their relationship publicly. Today, people researching Antonio Chi Su are usually interested in his biography because of his connection to Lyn May, his restaurant career, his illness, and the circumstances surrounding his death.
