Suthep-Thaugsuban-Chitpas-Bhirombhakdi-PDRC-Bangkok-Langsuan Leave a reply Khun Suthep Thaugsuban and Khun Chitpas Bhirombhakdi were marching all around Bangkok to support their group, PDRC. We were in Langsuan around 12 when they stopped to make some picture, collect money and talk with their fan.
