I have to say that the Spring Cocoon Stadium in Shenzhen does have many good activities, such as the Jiushiren concert before last week's birthday. This is Jiushi's first performance in mainland China. The collaborative Philharmonic orchestra has a large number of talents, and a solo violinist is very good. In fact, the only bad thing is that the tickets are too expensive, even if you buy more than 1,000 tickets, you still can't see clearly.
