First of all, the post-70s are a hard-working generation compared with the post-90s. You can make breakfast, dry cleaners, supermarkets, recycle second-hand waste, and send bottled water to the community. This kind of work is either to stick to the post for a long time, or to get up early and get in the dark. I once knew several post-70s entrepreneurs. They started to set up stalls to buy breakfast. Later, when the urban management refused, they rented a shop and changed to aquatic products business. The couple told me that they are almost 50 years old and it is not easy to find a job. The only way to go is to start a business. If they don't want to starve to death, they can only work hard.
