On a chance trip to Hong Kong for a program, Wu met his current wife, Gu Wei, who was still working as a choreographer in Hong Kong at the time. Gu Wei is also a Shanghai native and a former ballet dancer, and after they became lovers, they occasionally appeared together at Shenhua's training base. However, when Gu Wei comes to "visit", Wu Chengying always asks the photographer around him not to take pictures of his girlfriend. After a four-year love affair, Wu, who has always protected his girlfriend well, eventually married a beautiful woman, and Gu Wei followed him back to Shanghai after the wedding. Although Wu is seen as a loner by outsiders, at private gatherings of friends of Shenhua players, you can often see scenes like this: Wu meticulously serving dishes from a distant plate to his wife, or thoughtfully peeling shrimp for his wife. In addition to playing soccer, Wu, like many of his teammates in those days, planned his path after retirement. Perhaps because of the good genes of his math professor dad, Wu took the Shanghai college entrance exam with Qi Hong in 2003 and, as a special admission for sports, enrolled in the architectural design program at Tongji University.

In fact, when he was a player, Wu worked with a friend to open a company called Shanghai Jinying Catering Management Company, which includes hotels and restaurants. The Taoyuan Restaurant, located on the first floor of the Jinying Hotel at No. 523 Lujiabang Road in Shanghai, was once famous in Shanghai. And Wu Chengying is often seen in a restaurant he owns on Julu Road, a very moody part of Shanghai.

While the hotel business in Shanghai didn't last long, Wu's business on the mainland was put on hold for a while because of a partnership. And after the birth of their first daughter in 2003, the two shifted the focus of their lives to their children. But at the time, Wu was still playing soccer for COSCO, and in the time since the international move, Wu has become a typical "flyer".

In 2006, Wu and soccer drifted apart, but there was a surprise for his family when his wife gave birth to twin daughters in Hong Kong. Although he originally wanted a boy, he and his wife were thrilled to have twins in the family.

When Zhu Jun merged with Shenhua in 2007, Wu, who had already passed a physical fitness test and was preparing to return to Shenhua, was suddenly told that Shenhua would not renew his contract. Wu Chengying, who had been looking forward to returning to his roots, chose to retire without saying a word. After giving birth in Hong Kong and officially retiring from soccer, Wu and his wife shifted the focus of their domestic career to Hong Kong. On the mainland, however, Wu often returns for small get-togethers with her parents and brother. In recent years, Wu has sold her previous home in Shanghai, and the villa in the garden above where her parents used to live is said to have been re-let. His wife, Gu Wei, who has connections in Hong Kong, has also joined him in running his own business in the city. But after his retirement, Wu has not been idle, often running around Hong Kong and the mainland, and from time to time he and his old teammates to participate in some of the Enterprise Cup competition.

While he has been out of the game for some time, the low-profile Wu has recently been brought up again in the media, this time with the phrase "match-fixing case" added to his name.

Many insiders were surprised to hear that Wu Chengying's name appeared after Shen Si and Qi Hong's. In the eyes of many, Wu, who has never been associated with the outside world, should be the furthest away from this storm. Some fans even wrote, "If there is only one person in the Chinese soccer world who is not taken for a cup of tea by the relevant authorities, then that person must be Wu Chengying." But even so, Wu Chengying's name still raised alarm bells when it appeared in the press. When Shen Si and Qi Hong were confirmed to be taken away for investigation, the question of whether Wu Chengying, one of the four swans, was involved in forgery quickly became the hottest topic of discussion.

But in fact, Wu Chengying has not been arrested by the relevant departments for investigation, not to mention "hiding in Hong Kong" as reported by some of the media.

Wu Chengying was arrested by the authorities on September 22, 2010, in Shanghai Fengxian Huakai Country Club, during a "Expo Cup Parent-Child Golf" tournament. On 22 September 2010, Wu and her eldest daughter, Wu Jinyu, competed in the "Expo Cup Parent-Child Golf Tournament" at Shanghai's Fengxian Huakai Country Sports Club, and came in third in the E Division.

Interestingly, as soon as the father-daughter team got back to the scoreboard midway through the match, daughter Wu Jinyu immediately expressed her deep dissatisfaction with today's results, not forgetting to tell the reason: "Dad dragged me down by 8!" A helpless Wu Chengying could only bravely admit that she had not played well on the first eight holes, but also reminded her daughter, "I wasn't the one who hit the water on the last hole."

Wu, who was so popular on the green, was disliked by his daughter, who had no idea how popular her father was as a player in the 1990s.

Wu's external cell phone number keeps changing, and very few reporters can actually get through to him, so it's not curious to the outside world that Wu can't be found. But the man in the spotlight, currently at the center of the storm, doesn't really care about the outside world tracking him down, and never pays attention to outside news reports, but is now living the life he once idealized. "I'm living a comfortable life now, but I don't know much about teammates and counterfeiting and all these things, and I don't want to make comments." Wu Seung-ying, who lives with his three daughters, remained consistently calm as he answered questions about the counterfeiting and anti-gambling storm.
