Did you recommend a novel about a gang with the main character called Dragon's Might?

When I was young, I read a Hong Kong underworld novel. It was described in the first person. I think it's the best, most thrilling, and most attractive novel I've ever read! The protagonist was called Long Wei, Yamen, Annie, and others. The gangs involved included the Big Circle Gang, 14K, He Shenghe, Xin Yian, and other Hong Kong gangs. Long Wei was the boss of the Big Circle Gang. He told about his life in the underworld in Hong Kong and Thailand, and his relationship experience. In the end, he slowly changed for the better. Now, I want to read it again, but I forgot the name of the novel, so I asked. I hope that the readers who know can tell me that this is indeed a fascinating underworld novel. Family, friendship, love, and brotherhood are all portrayed in the first person. It is definitely a classic. I also recommend bookworms who have not read this book to read it. They will definitely not regret it!
