It's a lousy argument to suggest that Chinese products are bad because Chinese culture does not promote attention to detail because some people sometimes say "chabuduo". One can equally make the same bad argument about American workers, because some Americans use the expression "just eyeball it" at work.
When held to a high standard, Chinese people are capable of producing high quality products, evident in the prevalence of Chinese SWEs in FANG and the fact that Apple and Tesla both have major manufacturing facilities in China.
