The first advantage is free! This is a public welfare park! Free visit! The second point is expansion! It's really beautiful. It's very hard to design every partition! The third point is a good place to learn! Whether kindergarten children know plants, or a little older in sketching, observation, etc., is really a good place to learn! Disadvantages are: inadequate management; fewer resting seats in the new park, no place to rest; no volunteers or park service personnel to explain to tourists for the time being; many trees have just been planted, even the name brand has not been hanging; Desert Botanical area is best to build greenhouses, because Dongguan has a large climate change, abundant water in rainy season, occasional low temperature in winter, meat plants on temperature and humidity requirements. Higher, outdoor planting is difficult to ensure the best growth environment.
