It should be available everywhere, I'm not from Yunnan, but we have it here, so I can't help but see if there is one on Taobao or something.

And it is true that the air pot is placed at the vent of the pressure cooker, but don't you forget that the lid of the air pot also has holes.

Now the best way to do it is to put water in the pressure cooker, the gas cooker does not put a little bit of water, put on the very thinly sliced shredded ginger, shredded green onions, a little bit of salt, cooking wine, enough enough, this dish is to eat its fresh flavor, the pressure cooker's jet a little bit of the chicken's freshness will be forced out of the ...... wow!

Seasoning put more instead of adding to the snake.

All in all - it's safe to place the air pot at the vent of the pressure cooker! (Provided that the lid of the air pot is perforated, as long as a normal air pot lid is perforated, and besides, air pots are usually casserole dishes and won't be sealed like a pressure cooker).
