Where is Lin Chong's wild pig forest?

Many place names in the water margin do have their own merits, such as Liangshan and Jingyanggang, which are still in their original names; Happy forest, cross slope, as we also know, in Mengzhou, Henan; But Lin Chong was almost killed. Fortunately, where is the wild pig forest saved by monk Hua?

Lin Chong was sent to Cangzhou. On the first day, he walked "more than three miles" and then "three or two days". He lived in a small shop in the village and was forced to wash his feet by Dong Chao and Xue Ba (no massage). The next day, he went to the wild pig forest in Sanli and Wuli. It is the first steep place on the road from Tokyo to Cangzhou. I walked more in the last three days (even three days), say 50 miles, which is about 180 miles in total. It can be seen that this wild pig forest is more than 0/00 miles northeast of Kaifeng, Henan. Why the Northeast? Because Cangzhou is in the northeast of Kaifeng, it may be east or north, and then turn, but it can't be south. To the south? It was exiled to Yang Liulang, Yunnan.

We can also calculate that Lu flew an iron mord in the wild pig forest, and after Lin Chongfang's death, he escorted "17 and 18 days, but 70 miles away from Cangzhou". As mentioned earlier, Tokyo "went to Cangzhou for more than 2,000 miles", and Lin Chong left for about 22 days, about a hundred miles a day, but on the 17th and 18th, the monk named Lin Chong. Think about it. Under the supervision of Lu, "If you are a good person, you can scold, but if you are a bad person, you can fight". Why don't Dong Chao and Xue Ba, two unlucky people, try their best to push the cart? Therefore, it is reasonable to walk faster. So the wild pig forest is less than 200 miles from Fengfeng.
