Through the biennial Chile Mining Exhibition, we met nearly 50 merchants during this period, and nearly 40 of them had a detailed understanding of our company's products at the exhibition, and quotations were made according to the requirements of the merchants. And the customers interested in the company have been sorted out, the two sides have left contact information and information, which is convenient for later communication and cooperation. The general manager of the company traveled to Chile several times to negotiate with a number of customers and signed a large number of contracts. The performance of the company's sales company in Chile has been significantly improved. General Manager Wang Xuejun personally went to the LOMAS BAYAS mine site.
