Yi Yi has been practising law for 11 years and always focused on the legal affairs of marriage and family. She solved problems of marriage and family for more than 1,000 clients, accumulating rich practical experience. She has handled the divorce case of a shareholder of a large-scale real estate enterprise within one month and won more than 50-million-yuan property rights for the client; she also overturned the first trial where the client lost the divorce lawsuit (which meant the court ruled that the wife got no money) in the second trail. The amount in dispute was 2.3 billion and the case was unprecedented in the country.
