Which school district does Helan No.1 Middle School belong to?

If the house just around the school wall belongs to the school district, it's hard to say whether it's a few blocks away. Because the division of school districts in the street a little farther away changes every year, maybe this street belongs to the school district this year, but it won't be next year. It's better to buy a school district near the school, so how to divide it will not be drawn.
