During the 4th month or mostly when a baby turns one years old, there is an old Chinese custom where the baby step on a pair of kueh.The kuehs are pray to the gods first and with a new pair of shoes to be worn later prepared by the side, the baby is helped to step on the kuehs.

jiao ta does mean “step on”, after all. Cai,or “long and wonderful”, also means “step” when written with another character. Stepping on the Ang Ku-Kueh to symbolise that everything would be 顺顺利利 as the baby grow up gradually.
