There are two palindromes in Beijing Laoshe Teahouse. Who are they?

The two couplets in Beijing Laoshe Teahouse are also palindromes, so it is natural to read them backwards.

One pair is: "big bowl of tea at the front door, in front of the tea bowl",

This couplet embodies the site selection, tea-making methods and management characteristics of the teahouse, which is amazing.

The other pair is: "Lao She's guest house is full, but the guest house is full",

It not only points out the characteristics of the teahouse, but also skillfully introduces people's appreciation and love for Mr. Lao She's art, which is a must.
