Whoa. The Wuling mini is like 4,800 USD to 4,400 USD, while the Model Y is $48,447. That Tesla is selling only 300k Model Y's vs 500k Wuling Minis is actually pretty good.
I've ridden in a BYD EV taxi before back in 2016, I haven't lived in China since then. It was OK. BYD should have a larger market share than Tesla in China, it would be weird otherwise.
