Noodles have a big part in Chinese culture and history because they symbolize long life. They are always part of birthday or Chinese New Year meals because eating them is thought to promote longevity. The longness of the noodle represents the longness of life so the longer the better, especially for those occasions (what a tongue twister!). Never cut them because that would be cutting your long life short and very unlucky.
