You are correct that anything inedible is NOT used in preparing Chinese cuisine.
As to Chinese Baozi for breakfast, as mentioned by another poster above, there are many kinds.
And, probably, you CANNOT get them outside China, where they are cheap and plentiful, and available as early as 5:00 AM.
I am just sorry that I can no longer live in China, due to the political situation since 1949. Otherwise, I would live there 6 months a year, and Thailand 6 months a year....for the food if nothing else.
Someday, I may visit Italy, where I can have Italian food.... The Real Italian food.
Until then, no pizza for me here in Thailand.
I'm unable to tolerate the disappointment after purchase.
I have never seen a proper pizza oven in Thailand.
Wood fired pizza oven, I mean.
