Hundred-day swearing-in meeting refers to a large-scale teacher-student meeting held by students only 100 days before the national examination, which is mostly used for the 100-day swearing-in meeting for the senior high school entrance examination and the 100-day swearing-in meeting for the college entrance examination.

The 100-day swearing-in meeting is to enhance students' confidence in facing the exam, stimulate students' fighting spirit and promote students to devote themselves to preparing for the exam with a good attitude. Because of the college entrance examination in June, the 100-day swearing-in meeting was mostly held from February 28th to March 5th.
