He grew up in a poor farming family, he was introduced to Muay Thai by his grandfather with whom he would watch fights on the local television.
The first five months were rough as he didn't receive any training and kept doing various chores until the gym needed him as a last minute replacement.
After the win on short notice Jongsanan gained respect of the trainers, most notably of Monlit Sitphodaeng.
Jongsanan's promoter, Mr. Philip Wong, wanted this fight to be his rise to stardom, he trained harder than ever and managed to win by decision at Lumpinee Stadium on July 7.
