Teachers’day & Beijing Arboretum

It was teachers' day. Blessing to my IRLab teachers!
Chengjie Sun, Yumei Li, Pengbo Xu, and I gather at the door of Sigma with Mr. Changning Huang, who was an elder man of MSRA. We all expressed gratulation to him. He was very glad. Then we went to Beijing Arboretum by taxi. We went to Beijing Brboretum with us today. Mr. Huang had good body and physical force. He walked with us and talked humorously. He was in nice mood with us. It's a long-time walking.

Beijing Arboretum was very large, just like Harbin Arboretum. So many trees and plants were green now. There was a show of the 8th Miniascape and Stone enjoyment of Aisa Pacific. We saw so many surprise stones. We were astonished by their figures and artistic conception. When I got the pictures, I would share with you. There was a unique garden. It was a very big glasshouse. It was introduced that many intertropical rain forest were in it. But the door fee was very expensive. And somebody had been to it. So we decided to go in it another day.
