The curriculum system of Peking University gardeners is constantly updated with the market demand, and the timely adjustment of educational products is a major feature of Peking University gardeners. In the time of extensive contact with the employer, we often listen to the opinions of the personnel department of the employer, update the outdated knowledge structure in time, and ensure that every graduate has an absolute advantage in employment competitiveness. While upgrading educational products, teachers who undertake teaching tasks are also adjusting, constantly introducing new methods, new ideas and new energetic lecturers, and constantly optimizing the teacher structure.
