Just after the Spring Festival of the Year of the Rat, the newly renovated customer service laboratory was put into operation. Compared to before, the new laboratory is located in the Xinzhuang Hub with more convenient transportation. In order to better serve our customers, the new laboratory covers an area of 4 times larger than before, strictly distinguishes various functional areas, and runs more standardized and rigorous. At the same time, the laboratory has also passed a formal environmental assessment to ensure that customers can receive lasting and formal services.
