The topographic features of the city are as follows: 35.8% plain, 34.4% hills and 29.8% water. The main urban area is flat with a slightly higher elevation in the southwest. The elevation is about 20.0 ~ 28.0m and the northeast is low with an average of 1-3% on the ground. The western part of the main urban area is Xishan, a vein from the Jiuling Mountains in Jiangxi Province, showing a north-easterly pulse surge. Among them, the main peak of the drug washing dock (841.4m above sea level), Xiao Tan (799m), flower bud (704.9m) and Lei Gongjian (593.3m) constitute the main body of the Wanli Mountain. Meiling is a western mountain range in the northwest, with an elevation of 140 ~ 700m, with overlapping peaks and valleys, with a few days in the middle of the mountain. The temperature in summer is lower, with the name of “Little Lushan Mountain.” The above mountains are rich in bamboo.
