Link's agreement with Franco was that after obtaining a gold medal at the Olympics, he would then handle the yacht transfer procedure. To claim the yacht, Link had returned to the boxing gym to continue his training two days after taking a break.
However, after becoming famous, there seemed to be more things to deal with. One day after finishing his training, he received a phone call from Director Lin Yibin.
Director Lin said he had seen Link's impressive driving skills that day and asked if he would be interested in making a cameo as a racing driver in their crew.
Link was somewhat interested after hearing this. The Fast & Furious movie series had always had good box office returns, and the fourth installment seemed to have good reviews too. Being featured in this movie could be beneficial for his future fame. Besides, becoming an actor was one of his dreams, so making a cameo wouldn't be bad.
