Lin Yilun, a famous singer, asked curiously, "What kind of ghost light-off artifact is this?" Shao Hui explained: "It is actually a remote control light. Just replace the original lamp, replace it, and then use the remote control or mobile phone to remotely control it, then your home lamp will immediately become a remote control lamp. " There was warm applause for him at the scene.

As a liberal arts student, how could you think of inventing such an artifact that used a lot of science and engineering knowledge to turn off the lights? "This invention was invented out of laziness." Shao Hui told reporters that it is very cold in winter. In the school dormitory, many people are too lazy to get up and turn off the lights after reading books. Many students joked, "I wish I could turn off the lights remotely, so I don't have to get up so cold ..."

When the speaker is unintentional, the listener is intentional, so Shao Hui meditates. He borrowed a large number of related books from the library in his spare time and often asked the relevant instructors for advice. He knew the circuit like the back of his hand. After half a year's research, he finally invented the "remote control lamp" and obtained a national patent.
