Wuyuan is reputed as the most beautiful countryside in China. Its natural beauty reaches its peak in late March and April, when the land is covered in a colorful carpet of flowers.
Luoping is well-known to photographers, and is beginning to be discovered by average foreign travelers for the expanse of rapeseed flowers planted in the area.
