Berdos Bell Milk Cave, located on the north bank of Tuen Hu. To be honest, it is not as good as the Chinese cave. Probably no one here has found these things. I came here to really have the mentality of coming. I climbed up all the way and found that the Swiss Pass is not free. It seems to be a ticket for 8 Swiss francs. Come here, just take a look, that's the case, foreigners like it very much
