A teacher in central China created a phone holder by himself to live stream lessons to his students online during the COVID-19 outbreak.

In the video, shot by the teacher's wife in the city of Huangshi in Hubei Province on February 23, the teacher named Cao had a phone placed in a paper box that was hanging from his head.

The phone can be seen in a paper box attached to string and was hung onto Cao's head so he could show questions on the paper while writing and explaining the solutions.

Due to COVID-19 outbreak, the schools have been shut down and online lessons started.

2月23日，湖北黄石，受疫情影响，教师只能通过网络给学生授课，教数学的高中老师曹老师，因为一些电子课件讲课效果受限制，为了更针对性、更直观的给学生讲题，他用线和纸盒子自制了一个教具，挂在了脖子上（因为线勒得鼻子疼，在脖子后面垫上了儿子的厚袜子），这样一边用手写给学生解题，一边通过手机直播给学生，效果很不错。（视频由微信用户，曹老师的爱人“一眼望云舒”提供）
