What is the salary of Texas post office (not savings bank) after graduation from college? What about welfare?

When I first entered the post office, my salary was about 1.400 to 1.600, and it will increase to around 2000 in the future. Every Mid-Autumn Festival, we sell 2,000 to 3,000 yuan of moon cakes, 2,000 yuan of greeting cards and 3,000 yuan of newspapers and periodicals at the end of the year, and occasionally sell some mobile phone cards with pesticides and fertilizers. It doesn't matter if it doesn't sell.
