With the concept that "a person only gets married once in their life", the Pa Co people (A Luoi District) always consider the wedding ceremony one of the most important rituals to mark each person's maturity.

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.
