On the first day of the twelfth month, Langzhou submitted a memorial stating that the Jade Immortal Temple in Liling County had previously owned 20,000 hectares of good farmland, which had been blocked by rockslides for a long time. On the evening of July 17th of this year, a thunderstorm split open the rockslide, and the road was opened up once again.
