If the quality of your products is very good, it will also bring repurchase and referral, and increase your income.

In fact, the threshold of life circle of friends is the lowest, because everyone can send it, even a selfie or a landscape photo may let others know your life. This circle of friends is to make your life more real, otherwise no one will praise you in a circle of friends that is too professional.
