Is very simple inexpensive Beijing food for ordinary Joe, yet it tastes great and very hard to cook well.
First you need make very good lao4bing3, then cut it to threads.
Second to stir fry, you could use wu3hua1rou4 cabbage threads, with garlic.
I never had in US, each time back in Beijing, I look for a place with good chao3bing3.
Can great cooks make a such a simple dish?!
