Master Tai Chiang Ching has shown a keen interest in calculation using the abacus and mental arithmetic ever since he was a child. Even during his school days, he managed to attain the qualification of someone at advanced level. After retiring from the army, he devoted himself intensively to study calculation using abacus. He established CMA in 1984 and became the committee member of the Association of Children's Abacus Calculation in Taiwan the same year. He was awarded the World's Best Mental Arithmetic Trainer in 1991 and is also the President of Yu-Ming Publishing Co. Ltd.

He not only promotes the benefits of calculation with abacus and mental arithmetic, but also makes every effort to study the theories of them and development of new techniques. In 1992, Master Tai broke the traditional method of teaching calculations with abacus and mental arithmetic. To enhance learners' interest and learning results, Master Tai introduced a new technique which makes use of both hands to stir the abacus beads. This technique has been used on the mainland of China right up to Taiwan. He advocated this technique and became the pioneer in adopting the both hands method to stir beads thereby facilitating the balanced development of the left and right brain. The right brain which is not as frequently used as the left brain will be able to receive more stimuli when both hands are used to calculate. The children's calculating abilities, responses, speed and memory will also be facilitated.

Master Tai has been involved in mental arithmetic for 23 years and is the biggest mental arithmetic book publisher cum author. He has authored more than 200 books. Some people find this unbelievable, but it is a fact.
