brief introduction

Nailing horseshoes is a highly professional job. Before nailing a horseshoe, an experienced master will drive the horse to a special fence. This is because the horse's hind legs are strong. When people approach them from their hips, they will push people with their hind legs, and special fences can prevent horses from hurting the owners who nail horseshoes.

After fixing the horse, the masters usually trim and polish the horseshoe to reduce the pollutants on the horseshoe, and then nail it to the horseshoe.
