A private garden, named Wang Liyuan, was established by the descendants of Daishan, the second son of Hong, with a total area of more than 50 mu. In the early years of the Republic of China, Le Jia, the owner of Tongrentang, bought this garden as a private garden, so it is also called Lejiayuan, which is now a municipal cultural protection unit. The story of the Bai family told in the TV series Da Zhai Men is based on the music family of Tong Ren Tang. Therefore, the largest restaurant on the original site was also named Baijia Courtyard.
The front yard of Baijia Courtyard can be visited during meal time, but the backyard belongs to a senior private room and is not allowed to visit. The reporter saw in the front yard that there were rockeries, pavilions, flowers and trees, and waiters and waitresses in national flags shuttled through them, saying "You are so lucky" first. All the ancient buildings in the yard have been converted into restaurants, and now there are 42 rooms.
