The first disc of the meal is usually the raw fish salad. Slides of raw fish are to be mixed with the various vegetables. Some sauces and crispy crackers would also be added. Before taking that disc, everyone would stand up and use the chopsticks to mix the vegetables and raw fish. At the same time, everyone would say some prosperous words. That is what the Cantonese 'lou hei' (drag up) meant.

I have attended four of these gatherings recently.
