With the cold current（寒流） sweeping through China, temperatures（气温） in most places have dropped to the lowest（最低） level.

Despite the icy coldness（冰冷）, there are many people who stay in their posts（岗位） for the public good.

They are sanitation workers（环卫工人）, policemen（警察）, postmen（邮递员）, railway crews（铁路工作人员） , border guards（边防军人）…

Without their dedication（奉献） and service（服务）, we can never enjoy a safe（安全） and convenient（方便） life in such a freezing cold weather.
