All the way to Mengda Tianchi more than 40 miles, the road bumps provoked more yearning. But when I arrived at Tianchi, I found that the scenery along the way was better than Tianchi. The Yellow River running in the canyon, the villages on the bank of the river, the cliffs of the stone mountains, Mengda Tianchi is not large in size, and it is not possible to boat on it. The scenery is full, and there is such a peach place hidden in the continuous barren mountains. But I think it is better not to develop, dumplings are everywhere, tourists discarded drink bottles, film boxes everywhere. Since there are rich species here, it is better to leave them to those who need to study them and cherish them.
