Inquire about the mailbox of Liangshan Prefecture Governor

I am the owner of Jianxing Jinyuan Community. My house has been handed over for four and a half years, but the builder didn't give us the real estate license. He mortgaged our land certificate to SDIC for a loan of 25 million. So far, the land certificate is still in SDIC. Our owner, overhaul fund, 158 households, has collected business tax and deed tax from his personal account, which has been occupied by Zhao Chunping, director of the Meigu Family Planning Commission for many years, totaling more than 4 million. Now our host strongly hopes that the governor will do it for us.
