Ms. Zheng Guohua, the founder of Chinese Pastry King, entered the Xiyuan Hotel, which was relatively famous in the catering industry at the time, in the early 1990s and learned pastry techniques from Master Zhang Dachang, a first-class pastry chef. After two years of studying, he became a teacher of Du Jinhua, who was the only super pastry chef in Huaiyin City at that time.
