Dear Li Min,
How are you doing? Hope this finds you well.
Regarding the problem you told me in your mail yesterday, I have some suggestions for you. First of all, please wear decent clothes and be confident, which can help you win good impression from others. Secondly, always be honest and sincere to others, which is also very important when making friends. What's more, smile a lot. A good smile can make you more friendly and attractive. Besides, don't forget to participate in some group activities after class. By the activities with others, you can get along with them and make many friends.
I hope what I suggest can be really helpful to you. If you have anyhing want to share with me, please don't hesitate to write back.
Yours truthfully,
Li Hua谢了哈采纳吧，谢谢了嗯thank you
