From December 1st to December 12th, 2010, 4 people including Bai Haijuan, Wang Yuchen, Tian Li and Gong Xinghong from the company's sales department service center went to Xiamen Liyang Aquatic Technology Co., Ltd. in Guangzhou for a 9-day study. Mainly for the study of aquatic products. Courses include "Aquaculture Animal Viruses and Viral Diseases", "Aquatic Animal Pathology", "Aquaculture Animal Pathogens and Bacterial Diseases", "Pond Ecology" and "Aquaculture Medicines and Principles of Use". Through learning, I feel that I have gained a lot. Not only the basic majors have been improved, but more importantly, we have communicated with the employees of Xiamen Liyang, and have come into contact with some advanced breeding concepts. Some concepts have great conflicts with previous ideas. This requires us to continue to verify in future practice. Continuous improvement.
