Teahouse introduction: The Ganjia Teahouse on Shiban Street has been around for a long time, and you can see some of its history just from the mottled doors. Although the teahouse is old, it is a reflection of the real life of the people of Longtan. Old men wrapped in turbans sit in groups of two or three, smoking pipes or chatting and laughing, all of which reflect the comfort and calmness of this place.
