How to gracefully refuse the suggestion of driving and refuse to persuade wine?

There are many reasons for not drinking, such as allergies, illness, driving, and something at night. It's necessary to make excuses, but don't drink. After all, you are not so delicate as to have a glass of wine. For example, after the dinner begins, you can take the initiative to propose a toast to the leader and say to him, "Leader, I'm really sorry, I drove today. Well, let me show my sincerity first, and thank the leaders for their concern all the time, as you mean. " Pour yourself a little after drinking, and the people who come to propose a toast will usually inform you politely.
