I just watched a 1990s movie of Ang Lee, entitled Wedding Banquet, on my laptop. The movie was set in New York, but the main characters where Chinese. As the title suggested, it's related to a wedding banquet. I found the movie interesting as despite the characters being in a foreign land, they still carried out the main traditions of the Chinese. That reminded me of our own wedding traditions here in the Philippines.
Wedding banquets are indeed very important among the Chinese. It may be true to many other cultures. A banquet of sixty to eighty tables may already be considered grand. Chinese want a lively party, the more guests, the merrier.
