5:46 Uncle, I also play like your style. It's very good for returning a tight flipping net shot. The reason for going very low is to wait shuttle stablized(head eventually face down due to weight & gravity).
psst..... ask uncle ....two question....1.Why China always dominant,eg training method,school system......2.What makes Lin Dan so good.....can ask these 2 question to our local legends also can......
Back then Chinese more desperate to succeed. Ticket to a better life. Current generation not so good because China is now much richer and badminton don't offer much. Not enough to drive the desire. Look at things in proper perspective.
