What can I say? Did you really understand this question before you asked it? In order to answer this question, I went to official website, a Chinese-American college, to have a look. This Chen Meiyun is their technical dean, and there is no technical problem. Now that he has become the dean, he shouldn't be much worse. Are there any sequelae? I think the important thing is the later maintenance, and we must remember the doctor's advice after operation, which can greatly avoid the occurrence of sequelae. Hope to adopt!
