Which cities in China can get tax refund for purchasing health insurance?

At present, more than 20 cities have implemented medical insurance tax rebates. Specifically, the purchase amount of tax-excellent health insurance products is based on 2,400 yuan, and the insured is equivalent to the monthly tax threshold floating up and down in 200 yuan, rising from the current 3,500 yuan to 3,700 yuan, which means that the state provides subsidies for people to buy health insurance through tax reduction.
