Ningbo wanted to go the year before last, but the reason for that was not achieved. This time, I finally had time to see it. Tianyige is the earliest private library in China. It has a quiet environment. It has a mahjong museum. It shows mahjong in China, Britain, the United States, Japan and other countries. It is very beautiful. When you have time, you can come to visit. The ticket is 30 yuan. You can buy 27 yuan in Ctrip one day in advance, and then you can scan the two-dimensional code directly. About 1 to 2 hours of tour time.
