With many calling the Chinese topflight a "cheap" league, the striker was labeled a mercenary, for snubbing interest from top European clubs like Chelsea.
"Most people in Europe don’t see the Chinese League as a difficult one," Boakye said, as reported by Citinewsroom.
"You need to play in it to believe it [toughness], because I used to score a lot of goals in Serbia.
"I have played eight matches since [I came to China] and I have scored only two goals.
"This means that I have to work harder."
Boakye enjoyed a glorious time while in Serbia.
In a total of 30 league games involving 25 starts for Red Star, the 25-year-old notched an incredible 27 goals in two seasons.
He also netted four times in four matches in the Serbian Cup, in addition to eight goals in 14 outings in Europe.
