When filming The Karate Kid (2010), Zhenwei suffered a head injury requiring four stitches. He received it while chasing Jaden Smith (who played Dre Parker) after being splashed by the dirty water; Zhenwei hit his head on an oil pail. In addition, he received other minor injuries.
At the age of 4, his father sent him to the Beijing Shenshahai/Beijing Shichahai Amateur Sports School. After training for three and a half years, his father sent him to the Haidian Gymnasium and he began learning the national wushu routines.
When Zhenwei was 10, he came in first out of 57 excellent competitors when the national wushu team was searching for new members, and he successfully entered the national wushu B-Mannschaft.
Zhenwei received many awards in national competitions at a young age. He was awarded two gold medals in the Beijing Youth Wushu Competition.
