And they were often, along with onions and carrots, the only vegetables included in many Chinese American restaurant stir-fries.
They are commonly used in Cantonese cooking, but not so much elsewhere in China. Neither are onions.
Carrots a bit more, but not so much as everyone imagines. Every video for fried rice on YouTube seems to include carrots. Not usually used here. In fact, one way to say 'carrot' in Chinese literally means 'foreign radish'!
