Mao and Lin Biao on a calendar for 1967, with quotations of both of them:
"Wholeheartedly serve the people, not even a moment separated from the masses; everything starts with the benefit of the people and does not start from the benefit from one single individual or a small group, the compatibility of holding oneself responsible for the people and for the leadership of the party is our starting point. – Mao Zedong"
"Not only the soldiers have to study the “Three Old Essays”, but also the cadres have to study them. The “Three Old Essays” are the easiest to read, but to truly realise them is hard. You have to make the “Three Old Essays” to your maxim. No matter what class, they all have to study them and apply them, to do well revolutionising ideology. – Lin Biao"
