There was a scholar(书生) in Yunnan Province. He studied hard day and night on an island for an exam. His wife was very kind. She crossed a bridge to bring meals to him every day. It was far from their home to the island, so the food got cold and tasted bad when she got there. As time went by, the scholar was becoming thin and not in good health, so his wife was worried about it.
One day, the scholar's wife cooked chicken soup in an earthen pot(砂锅), putting in some rice noodles, some pieces of meat and vegetables. Unluckily, when she crossed the bridge on the way to the island, she fell to the ground and couldn't stand up for a long time. When she finally arrived, she was surprised that the earthen pot was still hot. The scholar was surprised too. They found two secrets: there was thick chicken oil on the surface(表面) of the soup and the earthen pot could keep the heat(热度) in. As a result, the soup was hot and delicious.
After that, the scholar ate well and became healthy. Finally, he did so well in the exam. Now, cross-the-bridge rice noodles are famous and popular.
