Huangdao District has relatively few people and it is relatively easy to rent a house.
It depends on where you are in Huangdao District.
You can take a look Newspapers, which contain rental information in development zones,
or find an intermediary, which is more convenient.
You can also go to universities. Many people who want to rent out houses go to universities. There are notices posted inside,
Go and have a look, and find a well-ventilated place, otherwise it will be too humid.
Bless you.
