Once upon a morning in Hong Kong, in the alley of Tai Yuen Street, a girl is promised a mooncake with a double-yolk center–the best kind!

The special mooncake seems like the only excitement on an otherwise boring day in the market where nothing changes… until an exhausted stranger falls to his knees right in the street! He ran through forests, swam through rivers, and even stowed away on a ship, all to get to Hong Kong. Now at the end of his journey, all he needs is a bite to eat, but no one seems willing to help–not even the girl, if it means giving up her prized treat.

The girl’s ultimate decision has surprising, far-reaching consequences in this mostly true story that reminds us that even the smallest acts of kindness hold the power to change lives, for the giver as much as the receiver.
