I want to know the answer to the following question:
What is the first river that the 40th, 3rd, and 6th Japanese divisions crossed while advancing southward?
All the background I'm provided with is that "In mainland China, the Japanese 3rd, 6th, and 40th Divisions massed at Yueyang and advanced southward in three columns and crossed the Xinqiang River, and tried again to cross the Miluo River to reach Changsha.". Is that enough to answer the question?
