What is the self-organization of travel agencies?

Self-organized and ground-based tour groups are legally sold. For example, self-organized foreign travel agencies come to East China and are sold to local travel agencies. When the ground connection travel agency sells to N cities, it is accompanied by the ground connection system. However, in many travel agencies, conference and exhibition service agencies and business service agencies in scenic cities (such as Huangshan Convention and Exhibition Service Company and professional one-stop conference and exhibition), they directly organize their own groups, such as foreign guests, business meetings and prize-winning tours. Instead of receiving foreign travel agencies, or only receiving higher-end foreign business awards. Such travel agencies or exhibition service agencies generally have a good reputation and the ability to organize tours, and the service is better!
