Hesi （荷思） is a student journal edited by students in the Department of Mathematical Sciences, Tsinghua University. The first issue was published in April 2008. In general one issue of the journal is published each half-year or a year. Also, there will be a special issue each year consisting of some undergraduate thesis of the students.


Hesi in Chinese means "Thoughts from Lotus Pond".
