Holiday Greatings

Christmas Greetings From Dr. Zhang

This video (my first xmas video) is not intended to be professional but I hope my message is clear and useful to you. Please leave comments or suggestions so that I can improve next year. I promise I will make this every year as long as I live and am able to do it. Before I make another one, I will review comments from previous year so that mistakes will not repeat and new ideas can be incorporated.
I would like to wish you and your loved ones a happy holiday season and New Year’s celebration, from Dr. Zhang
