On August 02, 2023, Customer from The Republic of Congo came to visit our company. Due to the urgent time, I took the customer to visit the company quickly, and then took the customer to catch the high-speed rail to Xuzhou to see the wheel loader and backhoe loader we talked before. During the visit, the customer has been making video calls to customers in Gabon to introduce our products. Customers expressed satisfaction. The next day, the customer asked me to make PI.
