WHY
Dr. Yang
Dear JulyGift:
I'm sorry to make you feel discomfort that your questions had been deleted. It happened due to the suggestion of my web site designer. Your questions in English caused some defect in program of message board so the web page became too wide and very hard to read. I was recommended to delete your message temporarily and I will answer your questions by Email as soon as possible. But I'm going to repaste those questions on the message board if the bugs in program has been removed.
Thanks for your forgiveness.
