With the development of the social economy, the market competition in the water industry has become increasingly fierce, and customer demands have become more diversified. In order to adapt to the ever-changing market environment, in 2023, Guolin's Customer Service Center actively changed its sales strategies and expanded its sales business. It established friendly cooperation with 14 water plants under Shanghai Fudan Water Engineering and Technology Co., Ltd., including Shanghai Fengxian Western Wastewater Treatment Co., Ltd., Pinghu Dushan Wastewater Treatment Co., Ltd., Kaifa Xinquan Water (Changshu, Dafeng, Taizhou, Tiantai) Co., Ltd., Ningbo Huangjiabu Coastal Wastewater Treatment Co., Ltd., etc., and signed annual framework agreements.

The signing of this framework agreement will contribute to the future performance breakthrough of Guolin's Customer Service Center and leave a deep impression at the headquarters of the water plants. Guolin's Customer Service Center will provide professional services and maintenance to the cooperating water plants through this framework agreement. Guolin Technology will also strengthen communication and collaboration with the cooperating water plants, gain in-depth understanding of customer needs, and improve customer satisfaction by providing solutions, technical support, and after-sales services, aiming for mutual benefits and win-win cooperation to jointly promote the development of the water industry.

Guolin's Customer Service Center is guided by the principle of "meeting customer needs" and provides worry-free services throughout the entire cycle of ozone generation system installation, commissioning, maintenance, and technical upgrades.
