In the clean and jerk category, he managed to lift 213kg weight to steal the show. In the snatch he lifted the 178kg to claim the bronze and with the total of 391kg he won the world medal.
In his first two attempts in the clean and jerk, he couldn't put up a good performance.

He looked as if he had lost control of the 213kg above his head again, but steadied and cheekily asked the judges if it was a good lift before dropping the bar.
Bulgaria's Ivan Markov with the total of 390 finished runner-up while the 20-year-old Russian Artem Okulov stood third with 385kg in total.
The world meet, which ends on November 16, serves as a qualifier for the 2016 Summer Olympics.
