The equipment that farmers needed for planting, cultivation, spraying, harvesting and transportation were no problem for him to build. He would repair any defective product, including replacing damaged parts, free of charge. "If a vehicle is defective, it means I didn't make it right. Of course repair should be a free service; I can't abuse others 'trust."
畢業後創立農機公司，凡農民耕種所需，從播種、耕耘、灑藥、收割、搬運需用的機械都難不倒他，產品一旦出門有問題他免費維修，損壞零件也奉送，「車子有問題，表示我做的不好，當然應免費服務，不能辜負人家的信任。」
