Reporter: Can you introduce your life experience?

Wang Guangjie: I was born in Jining, Shandong in 1941. After graduating from Jining No. 1 Middle School in 1963, I was sent to the Shijiazhuang Railway Institute of Military Engineering to study mechanical and electrical major. In 1974, I was transferred from the troops to the former third occupation middle school in Jining City to teach, and I was engaged in the teaching of electrical and electronic circuits.

After retiring in 1993, I was returned to a number of vocational schools for substitute classes, and I did not completely let go of the teachings until 2016. In 2021, because I was idle at home, and I loved electrical profession, I started to post teaching videos about electronic circuits online. In May this year, I started to teach on the vibrato.

Jimu Journalist: Many people think that doing live broadcasts is a matter of young people. You are over eighty now. Why are you still willing to toss?

Wang Guangjie: I have liked electricians since I was a child. I also studied mechanical and electrical major when I was in college. After graduating, I worked in electronic circuits for a lifetime. It is both my work and my biggest hobby. In 2021, it was inspired by some local netizens. I hope to use my professional knowledge to use the residual heat, start recording and publishing teaching videos, and later began to live broadcast.

Jimu News reporter: Have you encountered any difficulties when you live?

Wang Guangjie: I did n’t encounter any difficulties. I learned from the Internet through the Internet. No one provided help. The process of recording videos and live broadcast made me feel very happy. My video recording and live broadcast equipment only have one for a second -hand mobile phone purchased for 1,400 yuan, a mobile phone support for 5 yuan, a blackboard and a box of chalk bought at 50 yuan. In addition, there are no other equipment. The whole process of recording and live broadcast is also my own operation.

My body is very good, there is no problem with listening and vision, and my mind is very sober. In addition, the teaching work of electronic and electronic circuits that I have worked for a lifetime, the process of recording the video is very easy, which is easier than before.

Jimu News reporter: Have you encountered an accident in the live broadcast?

Wang Guangjie: I have made mistakes during the live broadcast. After the netizens pointed out, I immediately corrected it, and immediately acknowledged the mistake. I think this is normal and it is also beneficial to me. This is called "the teaching of teaching."

Jimu Journalist: In addition to posting teaching videos, do you also release other theme videos?

Wang Guangjie: In addition to circuit electronic and electronics teaching videos, I also often post some videos about the development of Jining urban development and rural scenery, hoping to let more people pay attention to my hometown.

Jimu News reporter: When you decided to live broadcast, did you think that you would become popular?

Wang Guangjie: I never thought of becoming popular before, and it was surprised by my expectations. I think my live broadcast and videos can become popular, not because netizens like my old man, but it means that the knowledge I spread is useful for society and netizens. After becoming popular, my life has not been affected and no change will occur.

Jimu Journalist: Will you always insist on live broadcast?

Wang Guangjie: As long as my body allows, I will continue to live. Living to old, learning old, live broadcast to old, I will work harder to learn new knowledge and technologies, and return to the attention of netizens and society with better works.
