By the next day there were hundreds of comments from my friends. They ranged from “OH MY GOD! That ‎ is so disgusting! ” to “What were they like？” to “Why can't you eat sandwiches like everyone else？”‎ To Chinese people, chicken feet are a normal snack. To my friends in Britain, the thought of eating a chicken's foot is——well, weird (古怪的). As weird, in fact, as eating a bullfrog, scorpion(蝎子), snake, or turtle.‎ But if there are two things I love more than anything else in life, they are trying new things and food.‎ I arrived in Beijing five months ago. Since then, I've searched for the “weirdest” foods so I can try them, then treat my friends to some “virtual(虚拟的)eating” on my blog.‎ One weekend, I went to Wangfujing, Beijing's “snack street”. The trip gave me tons of blog material.‎ ‎“I chose a stick with three live, wriggling(扭动的) scorpions on it，” I wrote. “ And it was pretty good. The scorpion was warm and crispy. The legs did have a tendency to get stuck between one's teeth, however. What's more, I am sure scorpion number two stung me with its tail in revenge(报复)．”‎ Next came snake: “ A bit like a cross between fish and chicken, with a slightly rubbery texture and meaty taste.”‎ Some people were actually angry when I ate turtle soup——especially when I posted pictures showing the poor little guy's head staring sadly up at us from the bowl. “ I am never speaking to you again，” wrote one (former) friend.‎ Still, I will continue my culinary quest. ‎ Next on my list is starfish, though I feel I should have some vegetables too—algae, maybe.‎ So what am I eating tonight you may ask.
