“Blue dye comes from the indigo plant but is even bluer.” Plant the indigo seeds and harvest twice a year, Squash the leaves in a tank of liquid, drain to extract the dye, hand print the cloth and make into clothes! Blue calico dying and batik printing are time-honored crafts handed down through generations. I wonder how many of you still remember them. “青出于蓝，而胜于蓝” 从一颗蓼蓝种子到两次收割， 打靛、起缸、染布、做衣！ 蓝印花布 蜡染这些老前辈们的手艺， 不知道还有多少人记得呢！
