? First, don't take off your shoes and enter the room? In the latest variety show in Jung Yunho, Yun Hao invented a little invention, you can enter the room without taking off your shoes. It's a small invention that doesn't need to take off your shoes and won't dirty the floor of the room. I thought it was shoes. So Jung Yunho took out something similar to a skateboard and began to slide into the room. Many viewers look like a joke. It turned out to be a little invention that allows you to enter the room without taking off your shoes!
Second, the mask with a smile has a warm smile? . This may be related to everyone wearing masks when going out during the epidemic, and people can't see each other. Jung Yunho printed a grinning mask and put it on his face as if he were smiling at a person. This invention is a very interesting job.
Third, the mask that can drink milk tea is very special. There is a cover in the middle. If you need water or drink, just open the lid and drink it without taking off the mask. At present, the patent has been successfully applied, which can be said to be Jung Yunho's second patent, so he is very creative. Some netizens expressed their great satisfaction with his invention. This is because the milk tea mask was originally introduced to satisfy young people to drink milk tea and drinks.
Many people think this design is very simple, so they never thought about applying for their own patents, but Jung Yunho applied for his own patents. This means that many people thought of this design, but didn't put it into action. Therefore, if you have an innovation, you should take action and apply quickly, otherwise others will apply. In my opinion, there is a market demand for these small inventions, such as smiling masks, milk tea masks, and tools for entering the room without taking off their shoes.
