On April 8, 2019, Dongsheng conducted health first aid knowledge training.

External teacher Zheng warned us through medical cases that we should always pay attention to our physical condition and treat problems in time.

He takes the human sudden coma as an example to educate us that 10 seconds of sudden coma can make people lose consciousness and 5 minutes may lead to brain death.

Teacher Zheng also teaches us some simple actions in the training process to judge whether there is a problem in his body, and the employees are actively involved in the interaction.

Through a simple test, Mr. Zheng told us: "Some diseases can be found in advance, we should treat them in time  . We can not delay the treatment, or else will leading to a terrible diseases."
