It is very hard for people from urban areas to understand the importance to treasure food. In the morning of October 7th, 2018, several HAS students went to Dashan, Miaoli for an agricultural event. Students had learned the farming procedures from modern to past, and the differences between organic and chemical farming. Apart from that, students went to a black beans field to help pick up weeds. Through this event, students not only experienced the hard works of the farmers but also understood how the agricultural products seem so precious and valuable. We really appreciate for having this chance to cooperate with the farmers in Dashan.
