1. Location: Qinhuangdao Oriental Pearl City is located in the north of Qinhuangdao, far from the city center, with inconvenient transportation. At the same time, the level of economic development in this area is low, and the surrounding commercial facilities are relatively simple. These factors will have an impact on housing prices.

2. Supply and demand: The rise and fall of house prices are closely related to the supply and demand. If there are too many houses in this area and there are relatively few buyers, then the house price will be suppressed, and the house quality and decoration level in this area may also affect the house price.

3. The developer's marketing strategy: The developer's marketing strategy will also affect the house price. If developers adopt a lower price strategy to attract buyers, house prices will also drop accordingly.
