Ceremonial occasions such as weddings, funerals, celebrations, beginning a big job, starting the ploughing and so on, all require a flick through the lunar almanac to choose the right date and time, and check which zodiac signs the time clashes with. People with those birth signs will have to stay away in order to avoid bringing bad luck into the proceedings.
像婚喪喜慶、開工、破土…… 等儀式，都要翻翻黃曆，選擇吉日良辰，並看看這個時辰衝什麼生肖，屬這種生肖的就必須迴避，免得引來凶兆。
