Why is Suzhou-Hangzhou group tour cheap?

Many scenic spots are free, such as the West Lake. Tickets for gardens in Suzhou are relatively expensive, and group tours are convenient and cheap. Participating in a group tour has many advantages, but the disadvantage is that lunch is generally poor (you can bring your own snacks or food), breakfast hotel is good, and dinner is solved by yourself. If shopping is easy to solve, just visit for free. No one is forced to buy it: Hangzhou usually buys Longjing or chrysanthemum tea. If you don't buy it, you can have a rest as free tea. Leather city will go, but generally don't buy the things inside, easy to be fooled; Suzhou may take you to the First Weaving Factory (the quality of silk quilts sold there is ok, so you can see them yourself) and the place where jade articles are sold (that is a deceptive place). Don't talk much when you go, come out after listening, not to mention buying), and there are temples that burn incense and worship Buddha. Don't think that you burn 20 cents with one wick of incense, and the trap is waiting for you to jump step by step. Just cover your pockets-in short, traveling with a group to a strange place is very convenient and cost-effective. Shopping will definitely take you there, but it is ok to keep a normal mind and not be greedy for petty gains. As for the reason of cheapness: a tour guide (two at most)+a driver to rent a car-the cost is very low, and a group of 40-50 people has considerable profits. Besides, there are so many travel agencies now.
