How do we know that? Don’t forget! Kids from our “Talent Village” are all geniuses! Based on those traces and clues we found in the mountains, we pieced together more and more stories of partisans. After further careful studies and researches, we concluded that those traces and clues are not left by our partisans by mere accident. Because these traces are extremely delicate and exquisite, which possess considerable aesthetic and narrative value. Those cannot be worked out by only one or two people. Partisans are writing a history for mountains deliberatively.
