My mom gave me a Chinese cookbook that had belonged to my dad. It had an old map, from back when Beijing was Peking. I immediately looked for Guangzhou.
It wasn't there.
But there was another city in the same spot, at the mouth of the Pearl River.
That's the old name for Guangzhou.
We spent two weeks in the city of Canton. My daughter is a native of the city of Canton. Of course, Cantonese things came from Canton!
