Until today, Zhang Heng had only two horse-riding experiences—colt he rode in the park when he was young. These colts were usually led by experienced staff and walked around the area at speed close to ten miles per hour.
In other words, this was the first time he chose a horse as a means of transportation. He was looking forward to the scene of riding a horse. From a safety point of view, Zhang Heng decided to do it step by step.
So he picked the shortest and thinnest brown horse with a hair loss problem. Compared to the other horses, it looked relatively docile. When approached, the steed showed no resistance, and as it lowered its head to eat, Zhang Heng walked to its side.
