However, with the issuance of the "Chongqing Municipal Government's Support for the Resumption of Production and Operation of Several Policies and Measures for Production and Operation" notice, relevant departments have taken multiple measures to steadily and orderly advance industrial enterprises to resume production.
Although the new coronary pneumonia epidemic had a severe impact on the Chinese economy in the first quarter, from the end of the first quarter, as the epidemic prevention and control achieved major stage results, the country mobilized all forces to prevent and control the epidemic and withstand pressure in a timely and orderly manner Promote the resumption of production and production, stabilize the Chinese economy, economic activities began to speed up recovery.
During the resumption of work, Chongqing Longjian Industrial Group formed an anti-epidemic leadership group, formulated anti-epidemic plans and plans, and actively purchased and stocked a large number of anti-epidemic materials such as masks and disinfectants. The chairman of the board, Mr. Long Fujian, cared for the employees, and personally delivered masks and other scarce materials to the employees' homes.
As of the end of March, Chongqing Longjian Industrial Group Co., Ltd. fully resumed production and resumed production. Its subsidiaries, workshops, and departments accelerated their efforts to inject a "strong engine" to accelerate the recovery of local economic activities. At the same time, in this special period, Longjian Industrial Group accelerated the production of orders, strictly controlled the quality, and won the time for customers to resume production. We firmly believe that the severe winter will soon pass, and "vitality" is still vigorous.
Recently, our Gansu cooperative customers from Gansu visited Sanming Heavy Industry Zone, picked up a set of PE750 × 1060 production line on site, and were eager to build a production line of 300 tons of high-quality basalt sandstones.

See the rainbow after the storm, the most beautiful spring dissipated in the cold winter. Under the leadership of the Party Central Committee and the whole country, all local enterprises have gone all out to fight the battle of resuming work and resuming production. Chongqing Longjian Industrial Group insists on "stabilizing production and emphasizing quality" to ensure that the company's development is "not disconnected" and fully promotes local economic development. Chongqing Longjian Industrial Group is in action to resume production after the war epidemic. While accelerating production, it will also start the quality voyage in 2020 again, so please look forward to it.
