Advice for today's "grassroots entrepreneurs":

If you are still young and are doing something that you are not sure can achieve long-term stable income, please remember to buy insurance.
Divide your money into three parts. One part is long-term health and medical insurance, including critical illness insurance, buy it for all immediate family members. This is the foundation to ensure that the sky won't suddenly fall on you.
Another part is long-term financial insurance. If you are the legal representative of a company, please designate the beneficiary as immediate family members (e.g., parents). When they need money urgently, the insurance can be redeemed early (losing part of the principal and all returns), or can be used directly as collateral for a loan (equivalent to using a deposit certificate as collateral, the interest rate is much lower than normal loans, and basically all green lights). If bad luck strikes, the company goes bankrupt and gets involved in economic disputes, the whole world knows you bought this insurance, but sorry, what cannot be enforced still cannot be enforced. This is your principal for "making a comeback and rising again."
The last part is used to maintain the project you are currently running.
Never have the mindset that "I earn so much money every month, so I will definitely be fine if a family member gets sick." For any serious illness, 50,000 is just a drop in the bucket, 100,000 is just the starting point, 200k is barely enough, 500,000 might be helpful, 1 million buys a chance, and 2 million might bring hope. Then look back at the "hard-earned" money you desperately earned, and you will understand what "a small fish compared to a big one" means. But by then, it's too late to regret. You don't need a lot of money; even the New Rural Cooperative Medical Scheme and basic social insurance are fine, especially if your parents work in informal units without insurance...
My father-in-law may have surgery tonight, and the cost is nearly 200,000.
Can you imagine the consequences without medical insurance?
