So I'm white my fiancee is vietnamese and we're doing a fairly traditional engagement party in a few weeks (the gold plates, the pig, I'm having an Ao Dai made etc). His family will also give the elders of my family the viet Husband and Wife Cakes or Banh Phu The, along with some tea. I understand the symbolism behind the cakes, but is there any special meaning or reason for the tea? I ask because I want to print up little tags explaining the gifts to help my family understand what they are getting. Thanks!
