During the Song dynasty (9601279), fortifications were constructed on the pass and the characters representing Mei Pass were carved on it. The Tang road was improved with brick paving. The surviving fortifications have the words "Majestic pass of Nanyue" () carved on the northern side and "First pass of Lingnan" () carved on the other side. (Both Nanyue and Lingnan are alternative names for Guangdong.)
