Watching videos is becoming a part of our daily life. Most of us like to watch them to relax or kill the time. Some videos are just for fun, some are news and some are short films ...
Two retired (退休的) teachers are well-known for making short videos. They make them to share knowledge.
Wu Yuren is a retired physics teacher. She has become known as “Grandma Wu” by making videos. She uses a humorous and easy-to-understand way to do physics experiments (实验) online. She is good at using everyday tools to experience the magical world of science. She wants young people to be curious about daily life. In this way, young people enjoy finding out the knowledge of science hidden in our life. Wu is more than 70 years old now but still works hard.
Wang Pinxian is an 87-year-old marine geologist (海洋地质学家) and teacher at Tongji University. During the past two years, he has used his videos to share his knowledge of the sea. He often studies things like the secrets of the Bermuda Triangle (百慕大三角) and whether there are sea monsters (怪物) in the sea.
These videos have been popular and thousands of people have watched and shared them. Many fans express their thanks for the chance to learn new things and stay in touch with the world around them.
