Evidence is not clear.

I think it is clear enough; please zoom the image by clicking it.

As what I wrote for WS2021-02878, the administrative system of Changsha City, Hunan Province (湖南省长沙市) once had a great change in the late 20th and early 21st centuries. The town mentioned in the evidence, 九江乡, now under the jurisdiction of Yuelu District (岳麓区) based on 湘民行发〔2008〕3号, and the name was changed to 含浦街道 (the previous name is 含浦镇) , and 学士街道 was also disassembled from 含浦街道. The geographical name related to the submitted character is written as 作肖/作硝/笮筱, and the material show the original name should be 筰筱. (See the entry of 作肖 and 笮筱大屋 on National Database for Geographical Names of China, and 作硝 is used in AMAP/高德地图.) I have not found the picture included the country name used in the country, so I can not confirm which names are proper.

The evidence is clear, but it is hard for me to understand the rationale of the submitted character.
