@Nutmeg031992 @LongDesertTrain Anyway, that was sort of a side issue, my main point was that there are interest groups who are resistant to either actually doing the work to upgrade ventilation or philosophically/politically opposed to any sorts of initiatives or requirements.
@肉豆蔻031992@LongDesertTrain无论如何，这是一个次要问题，我的主要观点是，有一些利益集团，他们要么拒绝实际进行通风升级工作，要么在哲学上/政治上反对任何形式的倡议或要求。
