The group journeyed around Dianchi Lake, fully appreciating Kunming's ecological beauty. They also competed in a series of games to compete for the right to answer questions in the "Dianchi Lake Quiz Contest," working together to achieve victory. At the Longmen Algae-Water Separation Station, the group witnessed the process of separating the algae from the water in Dianchi Lake. The "green paint" water, after undergoing a series of processes, became crystal clear before returning to Dianchi Lake. After experiencing the diverse agricultural tourism offerings of the region, the group embarked on a new challenge focused on Yunnan's "magical" cuisine.
