Tell me a reason why you use illegal uncertified China made ESP-8266?
Don't you want your development effort to be commercialised?!?

I have always understood that Expressif was a fabless Chinese company that designs innovative and popular chips.
It seems fairly likely that a lot of Chinese product designers and manufacturers will be based in Hong Kong, China. Taiwan, ...
They sell their devices throughout the world. And many people use them.
Since you are based in Hong Kong I guess that you will have local knowledge. I have always assumed that the chips and modules are manufactured to the highest standards. And sold at a very competitive price.
Not only do ESP32 and ESP8266 chips work well but the Expressif software tools are excellent too.
