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.
说实话,这取决于情况。如果一座建筑具有历史或文化意义,我认为它绝对应该被保护。但如果它只是一个没有特殊价值的旧建筑,那么也许可以考虑拆除重建。有时候,甚至可以保留外观,现代化内部,这是一种很好的折中方案。
