My advisor Ilya Pollak is just promoted to associate prof. Congratulations! Hehe, he treated us for dinner last night. It was a wonderful reastaurant, except that my dish is really bad. I should have ordered something else. I attach a photo here. Our group has four guys. The two very beautiful, seraphic girls in the picture are the wifes of two of my Shi Xiong. Hehe, lucky Shi Xiong, enjoying their life now!

 

Thank you so much, Ilya. Hope you can treat us another time:)
