Principles and boundaries of chat, you are a businessman, not a charity organization, you are an adult, not a beginner, just for profit. If others don't ask you actively, don't take the initiative to teach them how to be a person or how to do things. It's not necessary in essence. If others don't pay voluntarily, don't act as a mentor. It's not trustworthy in essence. If others don't pay, don't provide paid services. If you lose, who do you blame? If others come to freeload, don't provide services, only provide advertisements. Don't provide services to those who don't pay, only want to take advantage of you, and think that you are not capable, and think that your efforts are not valuable. People consider freeloaders, but no one considers your wife, children, and costs. You have morals, I have morals, you have value, and I also have value. It's a prerequisite for exchange. Set thresholds and filter out low-value people, and you will find that making money is actually very easy.
