Zhang was a delight to have as a guest - as were the three friends he brought with him. I was expecting only three total, but they all wanted to stay in the same room, so I pulled out a sleeping bag and a pillow for the floor in the king bed room, and everything worked very well. All of these young Chinese students were friendly, gracious and generous, inviting me to share the Chinese food they had purchased on one of the days they were here. They were also happy to share whatever they could about where they come from in China, and I was delighted for the socio-political and geographic insights they gave me. Since they liked Denver's shopping opportunities, I hope they return, and I recommend them all as guests.
