During the period of 1986, when Jacky Cheung released his first Mandarin record in Taiwan Province Province, Songhui Zhang was the propagandist of Xueyou, and Jacky Cheung stayed at Songhui Zhang's home when he went to Taiwan Province Province for publicity, and they established a profound friendship and revolutionary feelings. With the sales of Jacky Cheung records and the performance of Songhui Zhang, Songhui Zhang was gradually promoted to the general manager of Polaroid Records Company. In 2000, the record circle was reshuffled, Polaroid took over, and Songhui Zhang moved to Shanghai Record Company. At that time, Mr. Zheng Donghan, the general manager of Hong Kong Polaroid Records Company, jumped to EMI Records Company and waved to Xueyou. Xueyou chose Shanghai Records to support Songhui Zhang, and then Universal Records merged with Shanghai. Songhui Zhang can only be the president of Universal Records. Zheng Donghan, without Jacky Cheung, is still the owner of a record company, while Songhui Zhang, without Jacky Cheung, is just a small clerk, and the friendship with Jacky Cheung is firm to the end. So Jacky Cheung is Songhui Zhang's benefactor.
