Average salary in Shenzhen (2019) was 127K yuan, or about $18K usd. Average salary (manufacturing) in the US is about $30K usd.

I'm sure that after you adjust for cost of living, the numbers more or less look equal. However, keep in mind that manufacturing is leaving Shenzhen because of rising wages.
