In the 2006 iFox sponsorship case of the Chinese Super League, not a penny of the full 60 million yuan that year was recovered. At that time, it was Nan Yong who signed the contract on behalf of the Football Association. Nan Yong was responsible for this negotiation process. Yong is specifically responsible. However, in the contract that was changed in June 2006, it was Xie Yalong who signed and sealed the contract. At that time, the Football Association reduced Aifox's salary by 10 million yuan.

It is reported that at the beginning of that year, Nan Yong had been in charge of the sponsorship of Love Fox. Nan Yong later said that this was the best choice. In the end, Xie Yalong and Nan Yong reported the matter to the General Administration. Nan Yong spoke throughout the entire process, and he even "guaranteed that Love Fox will pay in the end." But according to sources, the two actually had conflicts on this matter. Before the final signing, Nan Yong asked Xie Yalong to sign, but Xie Yalong asked him to sign because Nan Yong was the leader in charge of the league. Xie Yalong's attitude was tough, and in the end Nan Yong signed.

However, there are many oddities in this contract. For example, the Football Association and the Chinese Super League signed a contract with iFox on March 12, but it was not until April that the Football Association and the Chinese Super League signed a contract with an intermediary company in Hong Kong. Agency contract, there is a time difference in the contract. This is a big question, because since the agency has appointed iFox as the title sponsor of the Chinese Super League, the Chinese Super League should first sign a contract with the agency, and then the iFox contract. Xie Yalong must be responsible for this.

What made the always cautious Xie Yalong compromise? Some people think that he gave in before interests. Legal experts analyzed that the Football Association and the Chinese Super League signed a 60 million yuan contract with the three-party general manager of iFox. It was not until 2007 that iFox remitted the first naming fee of 6 million yuan to the Chinese Super League. This is the only fee paid by Love Fox to the Chinese Super League. The remaining 54 million yuan has not been paid, and the other party has gone bankrupt. Even if it wins the lawsuit, it will lose more than 50 million yuan. Xie Yalong himself has committed the crime of malfeasance.

In addition, in June 2006, Aifox had negotiated with the Football Association to change the contract. Aifox proposed a reduction in the naming fee. They hoped to reduce the 60 million yuan to 45 million yuan. In the end, Xie Yalong and Nan Yong agreed to the request, and this time it was not Nan Yong but Xie Yalong who signed and sealed. It is reported that Xie Yalong did not intend to participate in the negotiation before, but he finally signed the contract to change the naming fee. This in itself was suspicious, and it was 15 million yuan less. He then resolutely refused at three chairman's office meetings. Taking Love Fox to court is even more difficult to understand.

Then on the issue of filing a lawsuit, until the decision to prosecute was made on September 1, 2008, Xie Yalong had a disagreement with Nan Yong on whether to file a lawsuit. Xie Yalong compromised at the beginning, but The two parties decided to file a lawsuit after three chairman's office meetings. Afterwards, the court found that Love Fox had gone bankrupt and the remaining 39 million yuan was impossible to recover. This was something neither Xie Yalong nor Nan Yong expected.
