When Yang Lan left CCTV to study in the United States, she married Zhang Yibing, a graduate student brought by her father (now working for Bank of China). At that time, they had a small house in Beijing, which seemed to be rented. After arriving in the United States, Yang Lan, like other international students, was lonely and nervous. Her husband is not around and she has no friends in America. Wu Zhi appeared at an accidental party. According to logical reasoning, Yang Lanxian had an affair. Later, she divorced Zhang Yibing. But Yang Lan's explanation is that she is too young to understand what marriage is. At that time, she was too young and simple. This reason is also valid. Zhang Yibing of China agreed to divorce after his wife divorced. Yang Lan and Zhang Yibing married Wu Zhi shortly after their divorce. Wu Lan has two sons now. The oldest one is Wu, who is 9 years old. The second one is her daughter, who is almost 6 years old. Wuzhi weighs more than 200 Jin, less than 166.

Wu Lan's assets in 1997 are less than $500,000; 1May 1998, Wu Zhi "invested" about 40 million Hong Kong dollars (about 5 million US dollars) to buy a 3% stake in ATV; Not to mention whether Wu Zhi's 3% stake in ATV is true or not, this is a question worthy of investigation. Even if the money is from his own loan, he can't turn all 3% shares of ATV into cash in more than a year. Moreover, the bank loan is not Wu Zhi's money, and he needs to pay back the bank. ATV's share price has not appreciated at all since 1998. If Zheng Wu really borrowed 40 million Hong Kong dollars, he would have to pay hundreds of thousands of dollars in interest. This shows the ability of two people to do business.
