After harvesting seasons, farmers in the village spend most of their spare time to knit "đó", a bamboo tool used to catch fish on the streams. This knitting handicraft has been handing over generations by generations in Thu Sy. The whole family participate in the process. While the mother and her sister are knitting "đó", the daughter helps father piling "đó" onto the bicycle. The father then rides the bike bringing "đó" to sell to other farmers in neighboring provinces. One bike full of "đó" could be sold for USD100. This traditional handicraft making process is in need of being maintained and reserved.
