A group of Tujia people suffered from the hardship caused by inconvenient transportation, and they told many sad and tearful stories during the long and long journey. Later, as the world changed, dragons danced and rainbows hung in the sky. Guizhou bridges spanned the mountains and rivers of Guizhou, turning the natural chasms into thoroughfares. This enabled the transition from "thousands of ravines" to "high-speed plains" and rewrote the history of Guizhou where "the land is not even three miles flat".
