Is Zhongshan a pilot city for Hong Kong to endorse many times a year?

Not an endorsement pilot city. Zhongshan has a small flow of foreigners and cannot be used as a pilot city for multiple endorsements in one year. The pilot cities with multiple endorsements a year refer to cities frequented by foreigners, such as Shanghai, Beijing, Guangzhou and Shenzhen. These cities can have multiple endorsement policies in the same year according to the entry situation of foreigners to facilitate foreigners to carry out business activities.
