壁垒森严
❶ 形容防守严密，作好战争准备，例我军防守严密，壁垒森严，敌人是攻不进来的。 Our defences are close and well fortified．It is impregnable and the enemy cannot take it． ❷ 比喻界限划分很严密，例公司各部门若壁垒森严，各行其是，则其行政、业务必定无法正常运作。 The different sections of this company are sharply divided and each goes its own way．Is it any wonder that the administrative and business sections cannot function normally? |
