I have been to Halin, 2oo9. Archeology-that many writers wrotes. This is a right spot that UNESCO had chosen. But there are many things to learn /study here- ceramic tiles and Kilns, (now obsolete), Sardaw Oak's (the King's overseer of salt production) his house where no nails were used and built over a hundred years ago, salt export to Western Yunnan, Snake cult, Manipuri invasion, mud pots and mud volcanoes,hot springs, Japanese occupation period, Four layers of inhumatioon, Jormon pots (earliest pottery)etc. etc. There will be no end to learn.
