Honestly, it depends. If a building has historical or cultural significance, I think it should definitely be preserved. But if it's just an old building with no special value, then maybe it's okay to replace it. Sometimes, it's even possible to keep the outside and modernize the inside, which is a good compromise.
老實說,這取決於情況。如果一棟建築具有歷史或文化價值,我認為它絕對應該被保存。但如果它只是一棟沒有特殊價值的舊建築,那麼可能可以考慮拆除重建。有時候,也可以保留外觀,內部現代化,這是一種很好的折衷方案。
