Next was the crossing of the Luding Bridge, about a 1,000 li to the north. A li is an interesting distance measurement. An uphill li is shorter than a downhill li. So, it measures how long the journey will take not how far. They had to beat Chiang to the river, and they did. Next was the race to the Luding bridge. It was an ancient structure built in 1701. This bridge is situated to the west of Luding County. The bridge measures about 100 meters long and 2.8 meters wide.

Thirteen chains supported the side supports as well as those for the bridge floor. Irregular planking lay on the flooring. The bridge is still there today. They had 100 miles to get to the river in two days and then take the bridge. Abandoning their equipment except rifles and bullets, they raced to the bridge. On the other side of the river, a KMT unit was also racing to the bridge. The KMT unit stopped for the night and the Red Army beat them to the bridge.
