Is Huilongguan a place where poor people live?

No. Beijing Huilongguan is both a town and a suburb. Because Huilongguan is a town under the jurisdiction of Changping District, Beijing, and because Huilongguan Town is located outside the Fifth Ring Road, it can also be said to be a suburb. Huilongguan Town has the largest community in China, with more than 300,000 people. So Huilongguan is not a place where poor people live.
