This should be aimed at everyone's specific situation. First of all, you need to know whether the other person's fitness intention is strong or not, and then know specifically what the other person's fitness purpose is and what his concerns are. For the purpose, you should introduce the effect of fitness accordingly, and ask the focus carefully, so it is generally easier to convince customers from two aspects. Try to make the customer feel objective and fair when speaking, and think of him from his point of view, which will make the customer feel comfortable and more convincing. Of course, it is very important to have some basic knowledge. The above are some of my experiences in private education, I hope to help you.
