This article belongs to the pure pornographic article, in which the emotional description is only embellishment. I prefer the scene of group communication, but the ability to control the text is really limited. The scene of four people can not be well performed. This is the first time I have written such a long article that I can’t control the structure. At the beginning, the characters were lost unconsciously. When I tried to find them back, I found that the amount of writing needed was too large. I was afraid that the writing would be more disorganized, so I simply gave up. I hope dissatisfied readers will forgive me.
