With the same value as Zèng cloth, the Amber sleeping mat of Ta Oi people (in A Luoi) also takes a lot of effort to produce. To make this product, sometimes the process of picking leaves, stripping, drying, dyeing, knitting… takes more than a month. Ta Oi girl, before coming to her husband's house, must have a few of these mats as an offering to show love and respect for the groom's family.
