Why do so many indoor playground manufacturers follow suit? The main reason is that the market of the indoor playground industry is large and the profit is high, the market entry threshold is low, and the technology requirement of indoor playground is low. Some low-end naughty burger products are the main targets for the imitation of some unqualified mischievous burger manufacturers. There are also many from the outside, casually adding their own trademarks, that is their own products, resulting in the user's distrust of the company and products. A large number of indoor playground imitations, that is, compressing some factories with independent property rights, will also bring trouble to the indoor playground amusement industry, increase users' judgement cost of the indoor playground, and cause the customer loss of the whole industry.
