[1] Wichannoi is remembered for being an fighting at the top competitive level of Muay Thai for an unusually long period of time, resulting in the nickname "The Eternal Yodmuay."

He is repeatedly heralded by renowned Muay Thai practitioners as one of the greatest athletes in the history of the sport with the likes of Samart Payakaroon or Dieselnoi Chor.Thanasukarn.

He then adopted the ring name of Wichannoi Luktalatkwan and fought in Muay Thai rules 10 times until he was considered a rising star and the gambler's favorite in Nonthaburi.

[2] He exercised active footwork as he pushed forward or moved backward, allowing him to be light on his feet like a boxer and easily throw punches as he quickly traversed in and out striking range.

[2][6][7] Wichannoi excelled at using fast, non-committal attacks such as lead low kicks and jabs to the head and body to control his opponent and manage distance like a Muay Femur fighter.

Wichannoi would use a variation of the teep, a side-teep, thrown to the opponent's hip which he would use to cancel kicks from southpaw fighters, a tactic that would later be used by Samart Payakaroon.

His manager Boonyiam Sophon worked to match him up against most of the top fighters at every weight division that he fought in, causing Wichannoi to become famous in Thailand.

Wichannoi captured the Rajadamnern Stadium junior lightweight title against Saifah Saengmorakot and defended it five times over four years, resulting in the Thai media labeling him as Jonghang Huang Kai ("King Cobra Who Guards His Eggs") in reference to his belts.

In 1973, Wichannoi's dominance reached a point where he ran out of opponents in the junior lightweight division, thus he began giving up to 20 lbs/9.07 kg so he could be given a chance to receive matchups once again.

[14][15] Hippy Singmanee cited Sasakul to be the most skilled fighter he ever faced, stating that his movement made it difficult to catch him[16] as he used evasive footwork tactics that most probably stemmed from Wichannoi's.

[1][19] After his retirement he became a real estate trader and successful businessman, becoming a millionaire, owning several-hundred-million baht businesses as well as making good investments.

[11] Wichannoi's older brother Cherdsak Iam-erb disclosed that he had taken his last breath at 8:45 pm of January 31, 2022 in Paolo Hospital in Phaya Thai district, Bangkok.

His funeral ceremony held at the Bang Phraek Nuea Temple had numerous attendants including various yodmuay such as Samart Payakaroon and Samson Isaan as well as former rivals Dieselnoi Chor.Thanasukarn and Pudpadnoi Worawut.
