I joined Yuanda Shuyang in 1990 and started working in light inspection. At that time, the conditions were extremely difficult, and the production equipment was outdated. However, no matter how challenging the conditions were, we couldn't let any unqualified products enter the market. To tackle this issue, we classified and screened all the unqualified products, compared them with national and industry standards through thousands of analyses, and carried out technological innovations for traditional light inspection methods and equipment. We established an internal control system for light inspection.

Light inspection is the final quality inspection process for transparent vial liquid medicines before they leave the factory. Light inspectors hold the medicine vials and inspect them under the light inspection equipment to check for any foreign substances, cracks, or impurities that would render the products unqualified.

I know that behind every vial of transparent liquid we produce lies the well-being of countless lives. If there is any misjudgment, unqualified products could enter the market and cause harm to patients. As a light inspection technician, I won't allow myself to make a single mistake. In my 30 years of working in light inspection, no unqualified products have entered the market.

At Yuanda Shuyang, my greatest achievement is that our drugs can help thousands of patients, curing their illnesses and gaining their trust in the Yuanda Shuyang brand. This is something I am proud and happy about.
