Senior high school students in Wuhan, the once epicenter of the outbreak of COVID-19 in China, returned to school on Wednesday, ending their three and half months of "holidays" at home. Together with senior students in vocational schools and technician training schools, a total of 57,800 students in senior grades are back to school.

All students have to have their temperature taken before entering campus. They also have to keep a distance of 1.5 to two meters between each other, according to Changjiang Daily. Masks are also required either in class or on campus.

High school students in Hubei's capital city started their winter holiday on January 20, and they were supposed to return to school on February 10. Because of the pandemic, students were quarantined at home and turned to online study.

Hubei, the Chinese province hardest hit by the coronavirus pandemic, will hold this year's national college entrance exam, or Gaokao, on July 7 and 8.
