Friends who don't play Weibo may not know "1 pan = 1 10,000 yuan/square meter" for the first time, but with the reprinting of reports in the paper media in recent days, this is called the latest "real estate appraisal unit" by the folk "rape flower" and is gradually known by the general public. Interestingly, netizens reacted quickly on Baidu Encyclopedia, and re-annotated the term "Pan" originally used as a surname: Pan, the abbreviation of "Pan Shiyi Unit", is a real estate appraisal unit, with one pan 1 000 yuan /m2 and ten pans 1 000 yuan /m2. As a key figure in the new entry, Pan Shiyi was named "Pan Qian Yi".
