Péngxī

Pengxi lies in the hills north of Suining, between the river systems of central Sichuan. Its county bore several earlier names before receiving that of Pengxi in the Tang dynasty. The Ming incorporated it into Suining in 1376, though the county was later restored; in the early Qing, Suining itself was for a time merged into Pengxi. The county gazetteer records that its walls, once built of earth, were rebuilt in stone at the beginning of the Jiaqing reign.
