There is no need to buy second-hand, you can contact the manufacturer of desks and chairs and buy some desks and chairs with lower price and simpler structure. New things will give people a different feeling, and decent second-hand will not be much cheaper than new ones. My children's weekend training places are all new, and it is said that they are made in Tengya, a local place in Wuhan. The price is not much more expensive than second-hand, which makes people feel practical.
