The key difference in the flora of China is...
4a. Leaves basally vaginate-sheathed; achenes not beaked. Ligularia
4b. Leaves basally not vaginate-sheathed; achenes beaked or not. Sinacalia
It is hard to see, but I don't see sheaths in these pictures, so I'm inclined to think you are correct with Sinacalia tangutica.
