That's right. It was just because of homework. Originally, I only wanted to see the source of the Pearl River, but I ended up taking the shuttle bus to Sanjiang Pavilion. I was able to see the Three Rivers and Four Lakes (Beipan River, Nanpan River, Niulan River, Dishui Lake, Huashan Lake, Pianqiao Lake, and Bailang Lake) and the world's largest compass. Not bad. After taking the shuttle bus back to the starting point, it's 300 meters to the right to reach the source of the Pearl River.
