Visit the valley in hot summer. When we first entered the valley, the sun was hot and there was hardly any cool place. Slowly walking deep into the valley, gradually see the shade, and then the vegetation flourishes, suddenly bright, as if into a fantastic fairyland may be haunted by elves.
The Erhera Canyon is a hard-to-find oasis on the Greime volcanic ash plain. Steep cliffs, clear streams, and abundant green vegetation are no exceptions to the scenery. But there are countless cave churches on the cliffs of the canyon, which will never be found in China. However, due to various historical reasons, it is a pity that the exquisite frescoes on the church have been destroyed.
