What kind of tea is the trunk dry tea brewed by the teapot in Foshan Restaurant, Guangdong Province?

Pu 'er tea or Liubao tea. Trunk dry tea is called tea stem (itself is the tender branch of tea tree), so it takes a long time to make tea. Its tea taste is different from that of tea brewed by tea leaves, and it will have a different feeling if you carefully distinguish it. Pu 'er tea or Liubao tea can be brewed with tea stalks and tea seed shells. But new tea drinkers still choose to make tea first.
