The Chinese old fire soup cooked with slow fire has enough calories and a long time, which not only takes the effect of medicine tonic, but also takes the sweetness of the mouth. She is a delicious soup cooked by women in Guangfu with various warmth, a health-preserving soup for regulating the balance of yin and yang, and a medicinal soup for adjuvant treatment and recovery. Guangfu, that is, Guangfu ethnic group, broadly includes 80 million Cantonese ethnic groups in Guangdong, Hong Kong and Macao and overseas regions (Cantonese-speaking ethnic groups from generation to generation).
