Introduction to Zhang Lingfu Command Post: On May 12, 1947, Zhang Lingfu, commander of the 74th Division of the Kuomintang, led his troops to occupy Menglianggu and used this cave as a field headquarters. Our East China Field Army launched a general attack on the 74th Division at 5:00 a.m. on May 13th. On the morning of May 15th, Zhang Lingfu abandoned the cave and retreated to the big stone wall on the south side of Dagoding and set up a temporary headquarters. The battle ended at 5:00 p.m. on the 16th. When cleaning the battlefield, it was discovered that there were Zhang Lingfu's relics in this cave: army beds, army nun coats, tables, chairs and tableware, bedroom cleaning supplies, as well as telephones, walkie-talkies, radios, paper and pen documents, the Kuomintang's "Central Daily News", Chiang Kai-shek photo frames, etc.
