The Guan Yin Temple in Chiang Rai.

In addition to the White Temple, Blue Temple, and Black Temple, this Guan Yin Temple in Chiang Rai is also worth visiting. There is a shuttle bus to the Guan Yin statue, and taking the elevator costs 40 baht. It's easy and convenient to reach the top of the 26th floor where the head of the Guan Yin statue is located. There are many murals on the second floor, which are definitely worth seeing. The abbot has spent all the donations on this temple and even established a hospital for people who can't afford medical treatment. It's a great story. You can also spend 100 baht to buy rice for donation, and a monk will bless you.
