My grandpa worked as a carpenter, who has devoted all his energy for carpentry for almost sixty years. Several years before, he began to make wooden models of farm tools. On National Day when I returned back and visited him with my parents, he showed me that he had created. He hopes he could expose people to the traditionally way of farming. Now every day, he prepares raw material in the yard, measures them, and polishes them. I’ve also picked up carpentry as hobby of mine. Now I am able to make a model by me. And I am determined to make it know to more.
