Painting is not only widely used in the commercial field, but also plays an important role in politics and society. For example, the lottery system is a common choice in public affairs, such as election and recruitment. By randomly selecting the credentials or number of participants, the final decision-making result is determined fairly and justly. Historically, it is not uncommon to draw lots to decide and resolve disputes. For example, in Historical Records, Wu Wu and Zhou Yafu, the son of Zhou Bo, competed for the position of the Prince of Emperor Wu of the Han Dynasty, and finally decided who would inherit the throne by drawing lots.
Although the function and significance of drawing is undeniable, there are still some disputes and problems. For example, some cunning merchants manipulate lottery vouchers or numbers to let their relatives and friends win prizes, thus achieving marketing purposes. At the same time, there are some unfair and unreasonable problems in the lottery system, such as not fully considering the abilities and conditions of participants in the lottery process, which leads to the final decision-making results biased towards certain groups. Therefore, as a random choice, lottery should be properly supervised and reformed to ensure its fair and just operation.
