Chaoshan Mountain is one of the top three places to view plum blossoms in Jiangnan. The plum blossoms are said to have the distinguishing features of "old, wide and rare".

'Old' refers to the fact that Chaoshan Mountain has two of China's five types of ancient plum blossoms: the Tang and Song plum tree.

The Tang Plum Tree is located in front of the fragrance pavilion. It is said to be the incarnation of a fairy named Jiangmei and to be over a thousand years old.

The Song Plum Tree is located in front of the hall of Great Brightness. The body of the original plum tree withered to a large extent, but did continue to bloom for a number of years. However, it has since died.

'Wide' refers to how Chaoshan Mountain had a wide swath of plum blossoms which extended for miles. Nowadays, there are still thousands of plum-blossom trees, and a variety of breeds, including scarlet, pink, red, and green. Some sources allege that "Plum fragrance can be felt within 10 miles" and that "Chaoshan plum blossoms are second to none".

The Chaoshan plum-blossoms are regarded as 'rare' because they have six petals, rather than five.

Cì máo ròuyuán (刺毛肉圆) is considered one of the most famous foods from Tangxi. It consists of meatballs and glutinous rice. It is said that this dish was invented by a local chief when the Qianlong Emperor once travelled down south from Beijing via the Grand Canal.

Xìshā yáng wěi (细沙羊尾) is a dessert consisting of fried dough with red bean paste inside. It is named after its shape, which looks similar to a sheep's tail (yáng wěi 羊尾).
