perhaps it is the plasticky yellow and red paints of these temples, somewhat common as well in China, Taiwan and SEA. i'm not sure if it is refurbished too. neither do i know enough of the culture there to differentiate whether they are subsequently built chinese buildings or are they truely local buildings of the petsi people (exonym: bai ethnic). it certainly feels better to see cultures and histories unique to their locations when you travel
I understand from the guide, the temples are all refurbished! Actually worse than that. It is a rebuild! a replica. If i don't remember wrongly, some of them are less than 20 yrs old.
