Eight o'clock in the evening is fine. At eight o'clock in the evening, most families have finished their New Year's Eve dinner and are ready to watch the Spring Festival Gala, so it is most appropriate to give out red envelopes at this time. New Year's Eve is an important traditional festival. During the Spring Festival, every household congratulates each other, having a family reunion dinner, eating New Year's Eve, putting up Spring Festival couplets, setting off firecrackers, paying New Year greetings, watching sketches and setting off fireworks.
