Introduction to the Rapeseed Flower Sea: The Rapeseed Flower Sea is a beautiful scenery in Hanzhong. The Hanzhong area is a traditional rapeseed planting and production base. Every year in March and April, millions of acres of rapeseed flowers bloom simultaneously in the Hanzhong Basin and shallow mountains and hills, which is a spectacular sight. Although it does not have the endless atmosphere of rapeseed flowers in Luoping, Yunnan and Qinghai Lake, it has its own unique beauty.
