Fruit of peace?? I strongly oppose that it is the result of National Ceasefire agreement which was signed two months ago. On the contrast, I'm in favour of, for a number of reasons, the result simply comes from the mindset changing of DKBA.
The most important reason is the waterfall is open for all visitors before signing. As i live in the border of Thailand near with Kyain State, I'd been there so many times before. No restrictions even for a foreigner. But they asked if you're from Burma or looks like Bamar. Although they ask some questions like where to go or why are you here, it's not too serious. If you say "waterfall', everthing is okay since that time.
Another reason is it's not under the total control of DKBA. It's the area of Myaing Gyi Ngu Monk. The monk who is very famous among thai and myanmar people as well as very influential on DKBA. So, that area is peaceful before ceasefire.
But, unfortunately, I don't know why it becomes popular only these days among your people. The waterfall is already famous in Thai people long long ago.
