They were loyal to their duties in the rescue work, which perfectly interpreted the spirit and will of the public security special police and people's doctors to regard death as home in the face of national crisis.As the disaster relief work continued to advance, Mi Ka saw the righteousness of the public security police from Xing Kelei, and Xing Kelei also saw the benevolence and benevolence of the people's doctors from Mi Ka, and thus he understood the responsibilities and missions of the other party more and more.As a police officer and a doctor, the two are once again in the same boat, willing to build a city for each other, remain loyal, and protect each other and the millions of people behind them.
