Now, the children's park does not need to join the fee. We just need to find a place with a relatively concentrated population, preferably a shopping mall, community, shopping mall and other places, and we can open our own children's playground. For example, a children's playground with a square meter of 100 only needs 7 to100,000, and the design and installation are all your own responsibility. We just need to open up the situation and start making profits in a year or so.
