On the north rim of Qinghai Lake, I saw fields and fields of this red-yellow crop. Vaguely, in the distance, you can see the Qilian Mountains which divides Qinghai from Gansu Province.
My driver and I stopped to take a look. He couldn’t remember the name of the plant. (Later he would recall that it was 油菜 (yóucài meaning “rapeseed” but this seems unlikely.)
Although beautiful, it had a pungent odor which clung to our fingers so much that we had to roll down the car’s windows.
