Mathematical riddles:

Mathematical riddles are a kind of riddle that combines mathematical operation knowledge and riddle-making methods. Cai Lun, courtesy name Jingzhong, was a native of Guiyang County in the Eastern Han Dynasty. Emperor Yongping of the Han Ming Dynasty entered the palace to serve as a minister. In the second year of Zhanghe (AD 88), Cai Lun was promoted to the rank of Zhongchangshi because of his meritorious services to the Queen Mother. Cai Lun summarized people's papermaking experience in the past and innovated the papermaking process, and finally made "Caihou Paper".

In the first year of Yuanxing (AD 105), he reported to the imperial court, and Emperor He of the Han Dynasty ordered the promotion of his papermaking method. In the first year of Jianguang (AD 121), he committed suicide due to a power struggle. Cai Lun's papermaking technology was listed as one of the "Four Great Inventions" in ancient China. It made outstanding contributions to the spread of human culture and the progress of world civilization, and has been respected by people for thousands of years. He is regarded as the originator and "paper god" by paper workers.

In Mike Hart's "List of 100 People Who Impacted the Process of Human History", Cai Lun ranked seventh. Cai Lun was listed among the "Best Inventors of All Time" published by Time magazine in the United States. The opening ceremony of the 2008 Beijing Olympics featured a special demonstration of the papermaking technology invented by Cai Lun. In addition, it is said that Cai Lun, who loved vertical multiplication, was determined to improve papermaking technology because his paper was often bitten by insects.

At the same time, the topic of "supplementing calculations bitten by insects" that he invented was called "insect-eating calculation" by the scholar-officials at that time. Therefore, historians generally believe that Cai Lun is also the originator of today's "number puzzle" problem.
