The rent is automatically adjusted by the market price, and the price bureau has no unified plan in this regard. Another, renting a house is a two-way choice. If it is expensive, you can choose not to rent it. If the government makes rigid regulations in this regard, it is possible that landlords are reluctant to rent their own houses. The state and the government can't force others to rent out their own houses, can they?
Therefore, this price issue is mainly decided by both parties through consultation and the market.
