In 2008, Liu Decheng from the Maryknoll Fathers Missionary School won the second prize in the mechanical and electrical engineering category of the 59th Intel International Science and Engineering Competition with the "Magic Anti-collision Lock", and was awarded the asteroid number 25073 by the International Astronomical Union. It is called "Liu Decheng Star". In recent years, he has changed careers, hoping to become a pilot. Although Liu Decheng did not continue to develop in the scientific research community, he still maintained the curiosity to enter scientific research. For example, when learning the principles of aircraft flight, he not only mastered the content of the principles, but also analyzed the reasons for the failure.
