As part of the much greater Liaoshen Campaign, the People's Liberation Army forces led by Lin Biao, in the areas surrounding Changchun, cut off roads, railways, and other routes of entry and egress to the Northeast, and cordoned off the city of Changchun itself. Though not surrounded by an ancient city wall, owing to the modernity of the city, the garrison had constructed, with the help of conscripted civilian labor a large moat, eight feet deep and twelve feet wide in 1947. The defenders, veterans of many campaigns against communist and Japanese forces, were considered crack-troops. Lin Biao deemed an assault on the city was deemed too costly and dangerous. Instead, communist forces decided to conduct a siege of the city, while preparing ambushes and traps for any Nationalist relief columns, using the city as bait. On May 24, the People's Liberation Army captured Changchun Dafangshen Airport thereby cutting off the air connection between Changchun and Shenyang. At the end of June, Zheng organized a wartime food control committee and promulgated interim measures for food control in the city during wartime which stipulated that the amount of food that citizens can keep for themselves can only last for three months, and the rest should be sold to the municipal government at a fixed price to ensure the needs of the defenders. If the measures were to be violated by the citizens, the food will be confiscated from the citizens if they are found with them and severe punishment will be imposed.
