There was a young man who lived in Mengzi, Yunnan. He was very smart, but he didn't like studying at first. His beautiful wife wanted him to study hard, so she made the young man live in a nice park. Then she cooked for him at home and every day she crossed a bridge to the park. It took a long time to get there, and she found the food cold when she got there. So she cooked a bowl of hot soup and took some rice noodles and meat there.
The young man found the food hot and delicious, and also liked it very much, and then he studied hard. His wife was very happy. She told this to other people and the meal was popular soon. People call it "Cross-Bridge Rice Noodles".
