Chengdu Shuangliu District Taxation Bureau. Baidu map shows that Lanrun Landmark Plaza is located at No.3, Section 1, Huafu Avenue, Shuangliu District, Chengdu, Sichuan Province. The tax bureau is a department-level unit, and the tax bureaus of districts, counties and county-level cities under prefecture-level cities are department-level units. Lanrun Landmark Plaza belongs to Shuangliu District, so I went to Chengdu Shuangliu District Taxation Bureau.
