回复：回复：Maybe both of them suffered from some kind of mental illne

Hi Deli,

Thank you so much for your kind words for me. You are truely an expert in the areas you are interested in. However, you always let me feel you are so humble and nice to others. I am blessed to have such a good friend like you.

The man ruuning in the picture you mentioned is not me (I should put a note there, not to mislead others). I downloaded the picture from the Internet. You are absolute right, YuGong is for 愚公, the foolish old man. YuGong is not smart, as we all know. What I admire is his persistence.

I am glad to hear that your computer is not mute any more. I'm still far from being good in English or music. But I am learning. It is said it's never too late to learn. Hopefully I can learn something from you and others here.

Regarding computer, I do know a little for I obtained an MS degree in CS in the US.

Have a wonderful week.

YuGong
