The seal existed before 2009. It's made of copper. It's exquisite. It needs 200 yuan. However, because there were many cases of posing as registered real estate appraisers before, it is now stipulated that real estate appraisers must sign their own names. If it is a mortgage, it is also required to leave the personal signature of the appraiser in the shortlisted bank for the bank to compare. There is no need to stamp now, so the professional seal is cancelled. If you think stamping is cool, it's okay to spend 20 or 30 minutes on the stall, but it doesn't make much sense.
