Recently, the temperature in Southeastern China’s Yunnan Province continues to climb, with the outdoor temperature over 40 ℃ for several days, and the surface temperature above 50 ℃. In such scorching weather, the public security officers were wearing heavy equipment to patrol the city streets and border. Their cheeks, necks and arms were tanned. “Even though I drink10 bottles of water a day, I still feel thirsty,” said Lu Zunding, a police officer.

A policeman is on duty at the checkpoint of Nanxi boundary river, border of China and Vietnam, and his neck is still scarred from the bite of tropical winged insects.

The temperature was over 40 ℃ in the daytime.

In the scorching temperature, a policeman was checking the motorbikes passing by, with his hands sealed by thick gloves, and sweat dripping from his face.

A policeman who was maintaining the traffic order in the hot weather had his shirt wet with sweat. His shirt goes through a cycle of getting dry and then getting wet again. .

An auxiliary police officer takes off his heavy helmet, showing that his hair and face are already wet with sweat.

In the hot weather, the policemen were “fully armed” to carry out security patrol and control work.

An on duty policeman at the police office of Longbo River showed no sign of laxity despite the burning sun.

The temperature at night remained over 30°, and the temperature difference between day and night is minimal.
