Being a very close friend of him, I personally learnt alot of things from Khing, academically and physically in life. He is a passionate guy and has the ability to influence people around him. I once heard of a quote made by Mahatma Ghandi - "Give me 10 men and I will shock the world", this quote is never exaggerate to describe what kind of person he is in my point of view. YES, I am telling you he is this influential. On the side note, he is a guy with decent look with numerous humorous ideas under his sleeves and that can make you laugh no day no night when you spend time with him. Adding this element into his teaching, I believe that his lesson will never be dull. As a friend, I admire his personalities and view on his own life. Dont worry, do your best and join his lesson, I can assure you to get whatever you wish to get from him. Cheers and gambatae!
