《礼记·礼器》
一献之礼是不够讲究的，三献之礼就有点看头了，五献之礼就礼数更加详备，至于七献之礼，那真是神乎其神了。
一献质，三献文，五献察，七献神。
The one-time offering ceremony is not exquisite enough, the three-time offering ceremony is a bit better, the five-time offering ceremony is more elaborate, as for the seven-time offering ceremony, it is really supernatural.
