We always believe that the development of China's container is a general trend, and is still in the early stage of development of the industry. A strong investment in technology research and development will put us in a leading position in the medium and long term and distance ourselves from our competitors. We have two utility model patent certificates. At the same time, the company is working with Lanzhou Jiaotong University, Railway Research, CIMC's expert team and a number of foreign-funded enterprises in this field to have technical cooperation and joint development of products. It is expected that in mid -2021, two new types of container equipment will be used in actual business. These technical equipment can replace the existing traditional transportation and handling modes, greatly improve the efficiency of transportation and handling, and reduce the transportation cost of customers.
