1948年尾到1949年頭，喺經過三大戰役，即係遼瀋戰役、淮海戰役同平津戰役之後，國軍嘅大部分精英重兵集團已經被消滅，解放軍軍力就大大增強，控制長江以北嘅大笪地區，開始準備渡江打仗。
From the end of 1948 to the beginning of 1949, after three major battles, namely the Vast Campaign, the Huaihai Campaign, and the Pingjin Campaign, most of the elite and heavy military groups of the Nationalist Army had been eliminated, and the PLA military strength was greatly enhanced, controlling the flea market area north of the Yangtze River, and began to prepare to cross the river to fight.
