Daofu County is nestled along the Xianshui River, where the river's relentless erosion over the years has created a series of fertile valleys, giving birth to a constellation of villages. The iGEM team's visit brought medical supplies and equipment to the villagers of Wa Ri Town for their daily healthcare services.</p>

As well, the iGEM team's visit brought medical supplies and equipment to the villagers of Wa Ri Town for their daily healthcare services.
+The iGEM team collaborated with local health clinics to conduct in-depth interviews and focus group discussions. Through accurate data collection, the team gained a comprehensive understanding of the recent trends in the incidence of hepatic encephalopathy and the current state of treatment in the area. Subsequently, we provided educational sessions on synthetic biology for the local villagers and held a popular science lecture on "hepatic encephalopathy" for them. To gauge the villagers' understanding and feedback on the knowledge of "hepatic encephalopathy" we shared, we visited villagers' homes for follow-up, hoping to further promote their awareness of the condition.</p>
