Our guide, Xing, was very responsible for the day trip to the Southern Cross-Island Highway. She contacted us beforehand about the activities, provided weather updates, and even helped us form a group. Our driver, Feng Ji, was experienced and helpful, taking photos for the group members and demonstrating excellent driving skills! (Tianchi, Zhongzhiguan, Southern Cross-Island Highway, Hinoki Valley)
