Where can I check the square of second-hand houses in Xinzhou?

Housing authority. According to the inquiry, Anjuke learned that. Xinzhou needs a real estate license to check the square of second-hand houses. I took my ID card to the Housing Authority (real estate trading center) to inquire. If it is not my inquiry, I need to write a power of attorney for real estate inquiry for notarization, and then bring the power of attorney, notarial certificate and original ID card for real estate inquiry.
