Li river is really a breath-taking scenery,pollution-free waterway though bothered tourists' intrusion each year. The best time to visit there should be from Sep to Nov.
So many tourists warm into this postcard picturesque place, and you have to push your way through the crowd to board the ferry. But it really deserved! Because it is a very rare experience to travel on a non-polluted river to see the breath-taking scenery.
Enjoy!!
