Comrade Lin Biao:

All units throughout the country should undergo a brief period of retraining, ideally lasting 10 to 14 days. Those that have already been retrained should do so again every month or every three months. All personnel of the Three Main Forces and Two Local Armies should be subjected to retraining once every one to two months, in order to build on their achievements, correct their mistakes, and better prepare for future combat.
