Due to unreasonable typesetting, I found that there were several more references on the last side of my preprint, which affected the aesthetics, so I made a new version
BibTeX does not have the right entry for preprints. This is a hack for producing the correct reference:
@booklet{EasyChair:9030,
author = {Zhanhao Jin and Xin Xu},
title = {Impulsion Assessment and Classification Based on EEG Features},
howpublished = {EasyChair Preprint 9030},
year = {EasyChair, 2022}}
