In the hot summer, it is not only the weather but also the enthusiasm of the trainees. The trainees did not fear the heat of the weather and were trained seriously. In order to better understand the product principle, better service customers do a good job in pre-sales and after-sales work. The 59th training has been successfully completed, and we will start a new phase in August. In order to better serve our customers and improve the quality of our products, we have never stopped working.
