Where to travel in March and April?

China is so big, but there are really not many places worth playing in March and April. Please recommend:

1. Fireworks were set off in Yangzhou in March, which is suitable for a two-day tour and there is no good place around.

2. The terraced fields in Guilin, Yangshuo and Longji are suitable for four or five days. At least there is more water than in winter, and the leaves are green.

3. It is suitable for Wuyuan to see rape flowers for two or three days, or you can go to other places in ancient Huizhou around, and arrange another two or four days to see where you have gone.

4. Hunan Phoenix.

5. Fujian sees Gu Lou.

6. There is only one day in the ancient town of Jiangnan water town in southern Jiangsu and northern Zhejiang, and you can go to the West Lake by the way.
