On March 8, 2023, a number of Korean businessmen visited Dongchen for on-site inspections. Chairman Luo Linhua warmly received them and led them to visit Dongchen Intelligent Production Base. 

Chairman Luo Linhua gave a detailed introduction to the factory's product production line, production process, and quality control. South Korean businessmen highly affirmed the quality of valves independently produced by Dongchen, the refinement of product processing, the excellent advanced equipment and the management of the workshop site.

Despite the language barrier, the two parties can learn from and communicate with each other in their understanding of valve products. Through this meeting, the Korean business partners expressed their willingness to establish a deep and lasting cooperative relationship with Dongchen in the future, and jointly develop domestic and foreign markets.
