As over 80 percent of the area along the coastline is offshore cage aquaculture area, he had to frequently take detours or shortcuts through cultivation fields, dropping the total kayaking distance significantly.
"But the coastline was always on my right, within my eyesight,” he said.
Tuo, from Southwest China's Chongqing, is a well-known extreme sports athlete in China, and especially famous for kayaking.
In August 2017, he and his friends spent 15 days making a kayak with advanced GPS and power systems. The boat is 5.8 meters long and weighs 30 kilograms.
Tuo paddled alone on the sea during the day and rested on the shore at night.
The average distance he traveled per day was 38 km. During the journey, he has weathered high and low temperatures, from 39 C down to – 17 C. His weight plummeted from 81 to 63.5 kg.
