What is the difference between a one-person one-room tour group and a special tour group?

Tell a professional like your brother not to ask. Generally speaking, there are many single-flying, single-sleeping planes, return trains or return trains. Special train is a travel agency that organizes people to travel to a certain place in order to charter a car with a depot of the Ministry of Railways. The special train is characterized by a large number of people. General special train 14 car can organize more than 800 people to travel together. The difference between the two is that there are few people in a single-bedroom team, and the overall cost of a plane is high, but it is easy and not tiring to fly. There are many people on the special train and the price is cheap, but it takes more time to go back and forth!
