You need it ~ otherwise they won't give priority to you. You can ask for their information at the consultation meeting. It is said that the internal regulations don't fill in their forms ~ even if you fill in your volunteer, it's useless ~ so you should be slow and steady ~ But if you fill in your second volunteer, if you are a high-scoring candidate who has not been admitted to Jiaotong University, Fudan University and Finance University, you will be selected by the university, otherwise this volunteer will basically be abolished. It is very important to fill in your volunteers. Please be careful.
