A rainbow-breathing dragon?

So after yesterday’s decisions, it was another long bus journey today. The owners of the homestay drove me to the bus station this morning and I arrived in Miri about 4.30pm. After checking in to where I’m staying, I went for a look around. The city is quite small. I found the oldest Chinese temple in Miri, dating from 1913, and just as I got there a rainbow appeared. There were lots of people coming and going from the temple, lighting incense and praying. I’m not sure if it was a special day or if people usually go to the temple in the early evening.
