On August 27, 15:00 Beijing time, all Chinese staff of NRW Project of Sri Lankan branch watched the online lecture on epidemic prevention and control abroad. We carefully watched the lecture and learned to find the weak links in the epidemic prevention of the project in combination with the project's own situation, so as to improve the prevention and control level. In the lecture, we also learned the scientific method to maintain the physical and mental health of the staff during the epidemic prevention period, and promoted and applied it according to the project situation. Through the professional guidance and Suggestions in the lecture, our project will have more strength to do a good job of "stability", more confidence to win the battle against the epidemic, and more confidence to make a contribution to "One Belt And One Road".
