Mung Mangkon (Dragon City) Gym was established by De Smith Food International Co., Ltd. with a heartfelt mission to uplift the local community and empower youth in Nakhon Sawan province.

We believe that Muay Thai is not only a treasured part of Thailand's cultural heritage, but also a powerful tool to create real-life opportunities - especially for underprivileged youth who lack access to proper training facilities and professional guidance.

With this vision, Jimjam Boxing was born - a gateway of opportunity for passionate individuals who dream of becoming professional fighters. Our goal is to help them transform that passion into a sustainable career and a better quality of life.

At our gym, we provide more than just physical training. We focus on discipline, education, and personal development ---- so that each fighter not only excels in the ring, but also stands strong beyond it, building a brighter, more empowered future.
