On September 15, 2023, the Hangzhou Asian Games torch relay around the province passed the baton in Wenzhou. The torch relay route started from "Songtai Square" and passed through Xinhua Street - Chan Street - Wuma Street - Park Road - Huan Cheng East Road - Anlanting (Ancient Port Site, Jiangxinyu) - Oujiang Road, and finally arrived at "City Balcony." According to the route, 15 torchbearers were arranged to complete the entire journey from "Songtai Square" to "Chan Street." The average distance each person relayed was 58 meters. If 58 meters is taken as the benchmark, the actual distance exceeding the benchmark is denoted as "+", and the shortfall is denoted as "-", referred to as the mileage fluctuation value. The table below records the mileage fluctuation values of some of the 15 torchbearers.
