Buying tickets is self-conscious, nobody cares if they don't buy tickets. Some monks will tear tickets when they enter the temple or not. I still buy tickets to support them. Children don't want tickets here. Very quiet, there are no visitors, you can quietly and carefully savor every part of the temple, the murals inside the Thangka architecture are worth a day to savor slowly. When we went, it was sunny in the morning and rainy in the afternoon.
