Shifu Yan Lei was visiting a temple in China when he saw a monk with this bag. He was impressed with how practical it is, fitting all his training gear as well as the Instant Health Massage Brush. It has a very simple Zen design. It can be used as a rucksack or a courier bag with one strap across the chest. Fully lined. Two pockets at the side to fit a water bottle. One zip pocket. The Chinese writing has a lot of meaning, which means, “If someone helps you, you should help them back.”
