Zhongshan Nightlife
Compared with Guangzhou and Shenzhen in Guangdong Province, Zhongshan is a little quieter at night. You can take a walk after supper along any street of the city. Taking some photos of the city at night will give you another impression. Don't worry however; Zhongshan still has a number of nightspots. There are clubs and pubs. Also in Italina DIY Zone, located at Tanzhou Town, you can find the first DIY jewelry park in China. While finding out about the long history and culture of various kinds of jewelry, you can design and make a piece for yourself. It will take you half an hour from the city center to get to the park.
Bars and Pubs
Lan Kwai Fang which has the same name as Hong Kong's, as its name implies, is the best place for you to have a drink in Zhongshan. A number of bars here also take the name of bars in Hong Kong, such as Will Will and Hei Club.
