An 83-year-old man Liem Wong Siu aka Djoni Matius or familiarly called by the name of Djoni Liem dubbed the super man 'toxic mouth thrower'. This expertise is owned by kung fu swordsman of the Ming dynasty.

The retired marine is capable of spraying poisoned needles, nails, fishing hooks, razors, rice or green beans from his mouth and is right on target for up to 35 meters.

When his expertise was attempted on November 19, 2017, the poisoned needle sprayed from his mouth was on target, stuck in a concrete about 15 meters away.

According Djoni Liem, this skill trained since the age of 6 years. Learned from his grandfather's friend a Kung-fu teacher named Than Chin Guan in Bandung. There are many requirements to learn about 'deadly bursts'. Terms of which must be strong and good physical condition, mental, biography, and psychological.

"I started training since I was 6 years old, with my grandfather's friend, and of the 35 students who last studied it lived 6. The 4 people did not pass, because the physical must be strong, sometimes this study can result in blood coming out of the mouth or ear. Who passed only 2 people, that is me and Ing-ing a woman. Ing-ing go back to China and from then on until now I am with him breaking up communication," Djoni Liem said.
