Hanzhong City relies on the Qinling Mountains in the north, the Bashan Mountains in the south, and the Hanjiang River runs through the whole territory, forming the Hanzhong Basin. Good natural environment provides unique conditions for the growth of rapeseed flowers. Every year in March and April, in the suburbs of Hanzhong and the counties under its jurisdiction, rapeseed flowers are blooming all over the hills and fields at the same time. It is like wandering in the sea of flowers.
