Ly020 (conTAct station ta) of course. At first, I changed my name to Brother Lingyuan (contact ta in the station). Ask the teacher in the academic affairs office. Children have different schools/systems. Liu (contact ta in the station). Is this important? Wangzhipengj (in-station contact ta) is basically not good for Liu Fudong (in-station contact TA). If you want to change your tutor for your undergraduate thesis, will your master tutor think you must be a restless guy? Undergraduate graduation thesis is nothing. Do not change it. For teachers, obedience and hard work are the most important. If you are disobedient, picky and picky, it is a betrayal and a shame for teachers to change tutors. You'd better not try!
