Wong Tai Sin Sign 51 · King Cheng's Playful Promise

This story comes from ancient China's Zhou Dynasty, around 1000 BCE. King Cheng was just a boy when he became ruler, playing in the palace gardens with his younger brother. During their games, the young king playfully cut a sycamore leaf into the shape of a jade tablet — the symbol of royal authority — and handed it to his brother, saying "I make you a feudal lord." It was just kid's play. But the court minister saw this and insisted the king honor his word, arguing that royal promises, even made in jest, must be kept to maintain the dignity of the throne. The reluctant boy king had to officially grant his brother a territory. This became a cornerstone story in Chinese culture about the weight of words and commitments. The tale shows how casual actions can have serious consequences, and how integrity sometimes means following through even when you didn't mean to make a real promise.
