Gong fu variations

Right now i only own a 75ml gaiwan and use standard western teaware otherwise. Id like to collect a gong fu set, but i‘m not sure what i want it to contain. I was interested how gong fu practices and teaware vary in different traditions throughout china, i know of the standard and chaozhou variety’s, but is there more? Also what is your favorite way to brew tea, aka what utensils do you use and what steps do you follow?
