西楼观天时，                                         
倏然大风至，                                         
暑气遽然去，                                         
凉意悄悄起。                                         
                                                               
忽而又冷雨，                                         
一滴再一滴，                                         
瑟瑟不由已，                                         
只怕要添衣。
