tea ceremony for both sides or only one side? to speed things up, may i suggest, get 4 cups (or more) ready for use, then get ur jie meis to help wash the cups, replenish the tea or take the cup from you as someone else passes u the next cups. And get someone to get ur relatives ready too... so u dont have to waste time looking for whos next.
ur solemnization is ends at 6.... the rest of ur guest can go for cocktail but then again, go for a 1 hour plus cocktail i a bit sian leh.. can u do the tea ceremony earlier in the day?
