On the morning of August 9, ZRCC CEO Mo Dingge went to the grassroot operation unit to carry out the "two-hour on-site" safety leading work. This model of tutor leading the safety has been the routine by ZRCC senior management every Monday. Mo Dingge emphasized that all employees must resolutely hold on to the "four bottom lines", make epidemic prevention and control the most urgent and top priority at the moment, tighten and compact responsibilities, and be cautious in grasping various prevention and control measures from the first beginning, strengthen emergency response, pay attention to safe production and environmental protection, and ensure the smooth and orderly progress of production and operation and construction.
