It’s really a big shock for me to learn this sad news that Wenbo left us.
He had full of energy and enthusiasm to explore wild and beautiful mountains as well as problems in mathematics. I had many memorable excursions with Wenbo in Jian-Kou Greal Wall near Beijing, in Calanques near Luminy, in Shandong’s Qunyu Mountain and Tai Mountain and everywhere with so simulated and interesting discussions. We still have several projects of explorations.
My deepest condolence to his wife and his family.
