            textAttachment.bounds = CGRect(x: 0, y: -4,  22, height: 22)
            
            attributedStrM.append(xingxing)
            attributedStrM.append(wo)
            attributedStrM.append(shi)
            attributedStrM.append(shuaibi)
            attributedStrM.append(NSAttributedString(attachment: textAttachment))
