I visited Shuiliandong with Don't Complain Travel. We took a taxi for a day from Tianshui and drove all the way to the entrance. There you'll have a little bus that can you to the Buddha Carvings. I've never seen something like that. You can continue all the way up the the "Water Curtain Cave" in which you will find a little temple with several houses. There's an old monk living there and it's a very quiet and beautiful place. We were offered some water from the holy spring, on which the last house is built on (we were able to look behind the wooden door). Definitely the highlight of my trip with Don't Complain Travel in China. Highly recommended!
