To facilitate tourists from Shenzhen and Zhongshan in the tour of Zhongshan city, two special tourism lines, the Sun Yat-sen Hometown line and the leisure sightseeing line, were set to open on July 1.

After several days of operation, Zhongshan Public Transportation Group decided to turn the ticket service from online to offline from July 4 on, paying by WeChat or cash in the ticket office with lower price.
