If you want to settle down, Chengdu is better. Now that the house price has not really gone up, you can buy a house. After you enter Chengdu, you will go to Chengdu as soon as your child is born, and then you can enjoy the preferential policy of studying in Chengdu.
As for the rent, it is directly proportional to the house price. You don't have to worry. Large investment and high rent. This is the law.
