Since the period covered Spring Festival, the traditional festival for family reunions, many students had to spend the time without family members for the first time in their lives.

"I missed home very much during the festival," says Chen.

They were still on duty on Lunar New Year's Eve, which fell on Jan 31, just a few days before the start of the 2022 Beijing Winter Olympics on Feb 4. After work, they organized a meal together, and celebrated a different type of Spring Festival.

They worked until the end of the Paralympics, which closed on Sunday.

The students have found the experience valuable. "This is not the first job I have tried, but it has taught me a lot, especially that one should not underestimate any work that seems easy and simple," says Chen.

"This experience has prepared me for more such work in the future. It has made me realize that working is not easy. It requires continuous learning and exploration," says Gao.
