B
Lai Yucheng is a 14-year-old middle school student from Changsha, Hunan Province. He has caught people's eyes by his great invention recently. He invented a special project: an intelligent birds-protecting and rodent control bait feeding device（智能防鸟误食灭鼠投饵生态监测装置）, and won a gold medal at the 123rd Paris International Exhibition of Inventions.
One day, Lai saw a bird die from taking poison（毒药）at his school. The poison was used to kill mice, but the bird ate it. So Lai got the idea of his project. He wanted to do something to protect birds from eating the poison.
“I noticed that birds and mice are active at different times—birds during the day and mice at night,” said Lai. With this in mind, Lai made the device to be powered by photovoltaic energy（光伏能源）. Photosensitive sensors（光敏传感器）control the doors, closing them during the day to protect birds and opening them at night for the mice. “This makes the device good for the environment and uses less energy,” said Lai.
Lai carefully put together his ideas and fixed his invention, trying many times to make it work perfectly. He used organic（有机的）glass to create the part for the bait（诱饵）as well as the doors for opening and closing. On the top, he left a special space for all the electronic parts. Lastly, he put the solar panel（太阳能电池板）on the top to power the whole set, and finished his smart device.
Chen Shuizhang, Lai's teacher, praised his hard work and problem-solving skills. “Lai is good at finding a problem in the real world and coming up with a cool solution. He keeps trying and fixing things until they work well, and he always plans things in advance carefully. That's what makes him stand out in this competition,” said Chen.
