I just visited Shanghai in this June. Yes, EV cars in China are much cheaper. As I did not drive these cars, I cannot tell the quality but I believe Tesla is still better. If it is not, why Chinese still buy it and Tesla sold the most EV cars in China. Also, Tesla is cheaper in China but they are made in Chinese factories. So, it costs less to make Cars over there also.

Here I also want to remind my American friends. The reason why China became so successful was because Chinese worked really hard. In last couples of years, the big Chinese companies talked about 996. It meant they started their days at 9 and ends at 9. They worked for 6 days on the roll. Rome did not built in a day. In order to keep our high living standards, we do need to work very hard to make sure we leave our kids a better future.
