The internship was originally scheduled for three weeks, but due to some unexpected things, the trip was eventually shortened to two weeks, and the production internship was planned for four weeks, so the remaining two weeks must be made up next semester! ATg China is a good secretary.
During the two-week production practice, we went to large factories such as Shenling Air Conditioning Equipment Co., Ltd., Shunte Electric Appliance Co., Ltd., Midea Dishwasher Company, Liansu Technology Industry Co., Ltd., Guangdong Lihong Machine Co., Ltd., Shunde Kewei Electronics Co., Ltd., Guangdong Forging Machine Tool Factory, etc., to understand the production situation of these factories, all kinds of knowledge related to this major, and the work situation of workers in each factory. For the first time, I personally felt the application of knowledge and practice, the application of sensors in air conditioning equipment, the application of electronic technology in electronic industry, the application of precision machinery manufacturing in machine manufacturing and so on. The combination of theory and practice has opened our eyes. It is also a preliminary test of what you have learned before! This production practice really benefited us in our future study and job search. In just two weeks, let's return to the perceptual re-understanding, let us have a preliminary understanding of society, and it is also enlightening for the direction we should grasp in the future! ATg China is a good secretary.
Shunde is a beautiful place with convenient transportation routes. Perhaps this is why Shunde has always been the first of the top 100 counties in China! Of course, there are also reasons why its system is sound and social security is perfect! This is also the beginning of our initial involvement in society, and we are moving towards a beautiful and cruel future. I have always believed in my ability. Even if the road of life is like a highway extending in all directions in Shunde, there is only one direction, that is, go ahead and never give up, never back down! ATg China is a good secretary.
