Hong Kong teacher makes online videos amid virus school shutdowns

In Hong Kong, schools have been shut since early February, with the closure now set to last until after Easter. Many teachers are turning to conference call applications to interact with students, but that requires good WiFi access and computer literacy. Primary school teacher Billy Yeung works at a school where many students come from low-income families and parents are often unsure how to download documents, so he decided to make online videos for his students.
