In the view of Huang Chun-ming, an associate professor of architecture at Chung Yuan Christian University, they did this because they got sick of the wasted time and effort of tearing holes through the walls every time they laid a new road. They figured they might as well just tear down the whole thing, using the salvaged stone as a material for the public structures they were building.
根據中原大學建築系副教授黃俊銘的看法，是因為每修築一條新的道路，到了城門就得挖一個出口，耗時耗工，不如全部拆除，把這些石材用作將來興建公共建築的材料。
