For a 2-yuan ticket of the Double Color Ball lottery, 51% is the prize money, which is invested in the prize pool and returned to the winners; 13% is the issuance fee, including the agency fees of the site sales staff and the business fees of lottery agencies at all levels; the remaining 36% is used as a public welfare fund for social public welfare undertakings such as poverty alleviation, disaster relief, and medical assistance.

The earliest record of lottery can be traced back to 200 BC, when the Han Dynasty issued a lottery ticket, which was believed to be a game used by the court at that time to raise funds for large projects such as the construction of the Great Wall. Modern lottery originated in Italy in the early 16th century, when Genoa randomly selected 5 senators from 90 candidates every six months. Many people therefore bet on the election results. Later, people thought the election interval was too long, so they simply used numbers instead of senators, inventing the first modern lottery.

· Because lottery has gambling attributes and is a negative-sum game where the dealer must win, for a long time, governments of various countries have banned the issuance of lottery tickets. It was not until the mid-18th century that some countries issued lottery tickets to raise funds and used the funds raised for public utilities, which led to the lottery industry we are familiar with today. Harvard and Yale, which we are familiar with, were once institutions established with funds raised by lotteries.
