The best Tourby movement is Seagull ST-8000, hands down. But it's expensive one, and it's low beat. Cage size - 13mm, off center hands.
#2 in my book is Hangzhou 3300, that we can see in early JLC reps, hi-beat, 16mm cage, off center hands.
Liaoning already stopped to make tourbies. Guangzhou Dixmont make ST-8000 under license, and 2 in-house tourbies, one manual, one auto.
Shanghai... Well, it looks, like cheap "open heart" movements, because of that bar holder across the cage... Meh...
ST-8002, auto version of ST-8000, same construction.
