Laldinsanga began boxing in 2016, initially for fun. Growing up without many friends, he often had to defend himself, leading him to explore martial arts, but boxing truly captured his heart. His breakthrough came with a state-level gold, earning him a spot with the Sports Authority of India (SAI). He won six state golds, five national medals, and the Best Boxer Award (2019). Turning pro in 2022, he is now the WBC Youth World Champion. Managed by Mujtaba Kamal and Grassroot Boxing, and guided by Coach Sete Renthlei, he aims to inspire the next generation, much like his idol, Manny Pacquiao.
