This and monkey king have beautiful hand drawn cel animation. With all that is known of anime in the west i am surprised Chinese animation remains unknown, or Korean. Today Singapore animation is used in a great deal of japan animation and the US but the quality is so poor to compare it to this would be criminal.

I blame the cultural revolution. Nezha was probably the height of Chinese animation unfortunately, it was all downhill afterwards.
Early Chinese animation was actually the inspiration for Japanese anime as I understand it.
At least we have Uproar In Heaven and this to give us a glimpse of what might have been..
