TOSSING YEE SANG

This is a dish called Yee Sang or Yusheng aka Lo Hei. I already had it twice ... 1st and 2nd day of CNY.  I don't think you can find this served in China nowadays as it is  common to South East Asian countries like Malaysia and Singapore.   It seems that there were dishes that bore a similar resemblance to it in olden China but this version is from my region.
Wikipedia has it that Yu Sang is a Teochew-style raw fish salad. It usually consists of strips of raw fish (sometimes salmon), mixed with shredded vegetables and a variety of sauces and condiments, among other ingredients. Yusheng literally means "raw fish" but since "fish (鱼)" is commonly conflated with its homophone "abundance (余)", Yúshēng (鱼生) is interpreted as a homophone for Yúshēng (余升) meaning an increase in abundance. Therefore, yusheng is considered a symbol of abundance, prosperity and vigor.
