How much does a father earn every month to support his family?

My dad graduated from junior high school and works in state-owned enterprises in third-tier cities, from eight to five. State-owned enterprises mainly focus on the sunset industry, which peaked about 5.6 years ago. Father can get close to 7000 yuan, and mother also had a job at that time, about 3000 yuan. At that time, there was no mobile phone, no online shopping, no school uniform and no makeup. Skin care products were probably facial cleanser. My mother washes clothes and dishes, and my father cooks. The food is good, four dishes and one soup, two meats and two vegetarian dishes. My home is relatively heavy, but fortunately, the state-owned enterprises send oil and rice, and there are meal tickets to the canteen to change barbecued pork and so on. Later, it probably started as a sophomore. State-owned enterprises are half-dead, and insects with a hundred feet are dead but not stiff. My father works hard for 5000 yuan a month, but my mother doesn't work. She opened a food store in Taiwan Province Province downtown, and she was helpless. Business is bad, so it's good not to lose money every month.
