"The story of "Little Big Soldier" comes from a sudden idea of Jackie Chan 20 years ago, during which he told this story to countless people including Ding Sheng. "After chatting with Ding Sheng, he decided to write down the story. I didn't pay much attention at that time because many people who listened to my story said they would write it down. To my surprise, a year later, Ding Sheng really brought the script for me to see, and we naturally agreed to cooperate."
