We usually help build up an on-site diagnostic center at the lead hospital in one of the four major therapeutic areas, namely pathology, infectious disease, genetic disease and routine diagnostic tests. We will also provide one to seven technicians to work at the center. In the meantime, the lead hospital will have one to seven personnel working at the center. If lead hospitals do not have sufficient capabilities and/or capacities to perform certain diagnostic tests, we will provide our expertise in diagnostic technologies, on-site staff, IT systems and testing equipment as appropriate to assist them to perform or upgrade the diagnostic testing at such centers.

Leveraging our knowledge of national and international diagnosis standards, we help medical institutions within the alliances to establish standard operating procedures to enhance their diagnostic testing efficiency and quality management in diagnostic testing.

We also offer on-site training and seminars to the staff of medical institutions within the alliances. These trainings primarily cover the standard procedures to handle test samples. We have also established an online consultation platform, under which our customers may upload patients' pathological reports onto the platform. We have engaged external pathologists to review these reports online to provide pathology guidance for hospitals and doctors.

We help medical institutions procure upgraded or new testing equipment to meet the increasing diagnostic demands and enhance their testing capabilities. Major testing equipment used at these on-site diagnostic centers are procured and provided by us. Generally, the testing equipment we provided to them shall be returned to us if the relevant service and collaboration agreement is expired or terminated.

We have established a smart Internet of things platform connecting our testing equipment, which can monitor the status of the testing equipment at these on-site diagnostic centers at our headquarters level. This platform will send the operation and maintenance data of testing equipment at these diagnostic centers to our system so that we can monitor the operating status of testing equipment to ensure the accuracy and efficiency of diagnostic testing, which we believe can enhance customer loyalty. In addition, we also formulated a hierarchical diagnosis and treatment module, which focuses on sharing information and allocating resources among medical institutions within the alliances through intelligent technologies. We will distribute diagnostic information to relevant hospitals online, and help hospitals direct patients to the most appropriate hospital for treatment. Our hierarchical diagnosis and treatment module involves a Yunkang telepathology platform, through which hospitals are able to conduct remote consultation, referral consultation and online transmission of testing results.

We also offer logistics services to deliver test samples to the on-site diagnostic centers from member hospitals. As these diagnostic centers are typically built at the lead hospitals, member hospitals may utilize our logistics services to deliver test samples to the corresponding diagnostic centers. In addition, if these diagnostic centers are not capable of performing certain diagnostic tests, the test samples may be delivered directly to our nearby ICLs for diagnostic testing.

Our technicians are involved in the daily operations of the on-site diagnostic centers to perform diagnostic tests at the centers. In addition, medical institutions may also use the diagnostic capacity of our nearby ICLs if these diagnostic centers are not capable of performing certain diagnostic tests. Afterwards, we will issue diagnostic testing reports.
