A shocking incident was happened in Beijing Zoo. I was visiting the zoo while I heard bears roaring terribly. I hurried to where bears stayed in. I saw the black bears injured and roll on the ground painfully. One of them was hurt too serious to move and feed. The people around were astonished. I learned this was a student from a famous university who cause the trouble. He poured sulphuric acid (硫酸) onto the bears while pretend to feed them. How a shame! Animals are our friends. Something must be done to prevent them from injured.
