At that time, Ya'an became the seat of provincial, municipal and county governments.

In October 1955, Xikang province was abolished and merged into Sichuan Province. Ya'an City and county coexisted. Ya'an City was directly under the Sichuan provincial government, and Ya'an county was under the Ya'an special office.
