Hakka Dish "suan pan zi" 算盘子

My mum made a dish call suan pan zi （算盘子）for our dinner . She is a Hakka. The name is suan pan zi because it looks like abacus...Haha...not everybody can accept it but I like it very much. The main ingredient is taro. Then it cooked with meat, mushroom, dried tauhu, sleeve fish slices etc.
