Antonio Chi Su was a Mexican-Chinese businessman and restaurateur who became known to the public largely because of his long relationship with Mexican actress, dancer, and vedette Lyn May. Unlike his famous wife, Antonio Chi Su generally lived away from cameras and entertainment headlines. His career was connected primarily to the restaurant business, while his personal life became part of Mexican entertainment history through his marriage to Lyn May.
Although many people search for Antonio Chi Su biography, relatively little verified information exists about his early life. His date of birth, exact birthplace, education, parents, and other personal details have not been firmly established in reliable public records. What is better documented is his work as a restaurant owner, his relationship with Lyn May, his battle with prostate cancer, and his death in 2008.

Who Was Antonio Chi Su?
Antonio Chi Su was a businessman who spent much of his professional life in the restaurant industry in Mexico City. He did not become famous because of movies, television, or music. Instead, his public recognition came through his relationship with Lyn May, a prominent Mexican vedette, dancer, actress, and singer.
Reports describe Antonio as a businessman of Chinese or Chinese-Mexican heritage. However, available sources do not agree on every detail of his nationality or birthplace. Some online biographies claim that he was born in Mexico, while others suggest Chinese origins. Because there is no widely available authoritative biography confirming these details, it is safer to describe his background as Chinese-Mexican or Chinese heritage rather than state an exact birthplace as fact.
Antonio’s relatively private lifestyle is one reason his biography contains so many unanswered questions. He was not an entertainer who regularly appeared in interviews, and much of the information available about him comes from reports about Lyn May.
Antonio Chi Su and the Restaurant Business
One of the clearest parts of Antonio Chi Su’s professional story is his connection to the restaurant industry.
Reports state that Antonio operated a Chinese restaurant on Avenida Bucareli in Mexico City. The restaurant became an important part of his working life and was also connected to his relationship with Lyn May. According to accounts of their relationship, the two first met around 1980, when Lyn May was working on a film near his restaurant.
Their meeting eventually developed into a long-term relationship. Antonio’s restaurant business also gave him an identity independent of his famous wife. While Lyn May’s career was centered on entertainment, Antonio’s professional world was focused on food, hospitality, and business.
This difference appears to have been an important part of their relationship. Antonio was able to maintain a quieter lifestyle while Lyn remained connected to the entertainment industry.
How Did Antonio Chi Su Meet Lyn May?
The story of how Antonio Chi Su met Lyn May is one of the most frequently searched parts of his biography.
According to reports, the couple met around 1980 while Lyn May was filming a movie in the area surrounding Antonio’s restaurant in Mexico City. The cast reportedly visited the restaurant, creating the opportunity for the two to meet.
Their relationship continued for many years before they reportedly married in 1988. Some sources give slightly different dates, so the late-1980s period is the safest way to describe the beginning of their marriage.
Their relationship brought together two very different worlds. Lyn May was a public entertainer known for her stage performances and films, whereas Antonio preferred business and a private personal life.
Antonio Chi Su and Lyn May’s Marriage
Antonio Chi Su and Lyn May reportedly remained together for approximately two decades, with some accounts describing their relationship as lasting around 25 years.
Their marriage became one of the most significant relationships in Lyn May’s personal history. Even years after Antonio’s death, Lyn has spoken publicly about the affection she had for him.
Reports describe Antonio as a supportive and caring husband who preferred to stay behind the scenes. His life was therefore quite different from the glamorous public career of Lyn May.
The couple’s story continues to attract attention because it combines romance, business, Mexican entertainment history, and a deeply personal experience of loss.
Did Antonio Chi Su Have Children?
Information about Antonio Chi Su’s children and family is not consistently documented.
Some online sources make claims about children or stepchildren, while other biographies state that there is no publicly verified information about his biological children. Because these accounts conflict, it would be misleading to present a specific number of children as an established fact.
The safest conclusion is that detailed information about Antonio’s wider family—including his parents, siblings, and biological children—has largely remained private.
Antonio Chi Su’s Illness and Final Years
The later part of Antonio Chi Su’s life was marked by serious illness.
According to multiple reports, Antonio was diagnosed with prostate cancer in 2004. He continued dealing with the disease for several years before his death in 2008.
His illness was an extremely difficult period for Lyn May. In later interviews, she discussed the emotional impact of losing her husband and described him as someone she loved deeply.
Antonio eventually died in 2008. Public reports identify prostate cancer as the cause of death.
Because Antonio was a private person, detailed medical information about his treatment and final days is not widely available. Claims beyond the basic diagnosis and reported cause of death should therefore be treated carefully.
Antonio Chi Su Cause of Death

The cause of death of Antonio Chi Su was reportedly prostate cancer.
He was diagnosed with the disease in 2004 and died in 2008 after several years of illness. This information has been repeated in biographies and entertainment reporting about Lyn May and her late husband.
His death marked the end of a relationship that had played a major role in Lyn May’s personal life.
Why Is Antonio Chi Su Still Famous?
Antonio Chi Su was not a conventional celebrity. His continued popularity comes mainly from three areas: his marriage to Lyn May, his restaurant business, and the stories surrounding his death and Lyn’s grief.
Lyn May’s long career has kept her name in Mexican entertainment discussions, which naturally brings attention to important people from her personal life.
Antonio’s story is particularly interesting because he represents a different side of celebrity history. He was connected to a famous entertainer but did not build his own public identity around fame.
Instead, his legacy is associated with entrepreneurship, family, and his relationship with Lyn May.
Antonio Chi Su Net Worth
There is no reliably verified public figure for Antonio Chi Su’s net worth.
Some websites publish specific estimates, sometimes claiming that he was worth millions of dollars. However, these figures generally do not provide financial records, business valuations, property documents, or other evidence that would allow the numbers to be independently confirmed.
Antonio owned or operated restaurants, which indicates that he had an established business career, but restaurant ownership alone cannot establish a person’s personal wealth.
For that reason, any exact Antonio Chi Su net worth figure should be regarded as speculation rather than confirmed biography.
Antonio Chi Su Name and Spelling
People searching for Antonio Chi Su may encounter several versions of his name, including Antonio Chi-Xuo and Antonio Chi.
The spelling “Antonio Chi Su” is widely used in English-language online searches, while “Antonio Chi-Xuo” also appears in Mexican entertainment reporting. Available sources generally treat these names as referring to the same person.
Using the most common spelling, Antonio Chi Su, makes it easier for readers to find information about him while acknowledging the alternative forms.
Legacy of Antonio Chi Su
Antonio Chi Su’s legacy is not based on a long list of awards, movies, or television appearances. Instead, it comes from the life he built away from the spotlight and the relationship he shared with Lyn May.
He was a businessman who worked in Mexico City’s restaurant industry, a husband who remained important to one of Mexico’s best-known entertainers, and a private individual whose story became public largely after his marriage and death.
His biography also demonstrates the difficulty of researching people who lived outside the entertainment industry. Many online claims about his birth, age, nationality, family, and wealth are repeated without strong documentation.
The most reliable picture is therefore a simple one: Antonio Chi Su was a businessman and restaurateur of reported Chinese-Mexican heritage, best known as Lyn May’s husband. He operated a Chinese restaurant in Mexico City, married Lyn May in the late 1980s, was diagnosed with prostate cancer in 2004, and died in 2008.
