According to Chinese folk traditions, elders typically give red envelopes (known as "lucky money") to children during the Spring Festival, symbolizing blessings and good wishes for the coming year. Nowadays, red envelopes are not just gifts for children but also commonly exchanged among elders, relatives, and friends. In recent years, with the growing number of WeChat users, digital red envelopes (WeChat hóngbāo) have surged in popularity. During Spring Festival celebrations, people frequently send WeChat red envelopes to exchange greetings—a convenient way to connect with distant family and friends.
