My home town is Wuyuan, a county in the northeast of Jiangxi Province. It is more than 1,000 years old. And there are more and more tourists visiting it these years.
In these villages, there are many old buildings with black tiles (瓦片) and white walls. Every year, many students come here to draw them. Another place people like to visit in my home town is Rainbow Bridge. The bridge is over 800 years old. It is 140 metres long and 3 metres wide.
We usually take a walk in the sea of rape flowers (油菜花) in late March and early April. In summer, it's very cool in the mountains, so we like to go there to have a picnic. Wuyuan is very beautiful in late autumn too. From October to late November is the best time to watch red and yellow leaves in the mountains.
Wuyuan is not big or busy. It only takes us about two hours to arrive in Hangzhou from Wuyuan by bullet train.
