"Kuilongzhu", founded in the early years of the Republic of China, is a representative of Yangzhou Fuchun Tea House and the symbol of Yangzhou people's ingenuity and innovation.
Kuizhen is produced in She county, Anhui province, which is the birthplace of Xin'an River. Longjing is produced in Hangzhou, Zhejiang province, where Qiantang River is located at the foot of the mountain. Zhulan is produced locally in Yangzhou, where Yangtze River runs inside.
Therefore, "Kuilongzhu" has the reputation of "cooking three rivers in one pot".
