Mr.Chen living next door to us has a habit of drinking. The best present to him, of course, is wine, Now his eldest son brought him a bottle of Mao Tai. He was glad and stared at it for some time, then wrote “105” on the corner of the trademark with a pencil, meaning he had already drunk 105 bottles of the famous wine. Two days later a stranger came. He offered to pay 5 yuan for the empty Mao Tai bottle. Mr.Chen was pleased and sold it. Several weeks later, his second son brought him another bottle of Mao Tai. While examining and enjoying it, he was suddenly terrified—he found “105”—the very mark on it.
