            [zhōng guó lián tōng lián bù tōng zhōng guó yí dòng yí bù dòng]
        
        
            The phrase 'Zhōngguó Liántōng lián bù tōng Zhōngguó Yídòng yí bù dòng' humorously means 'China Unicom can't connect; China Mobile doesn't move.' This is a play on words referring to two Chinese telecommunications companies and suggesting unreliable or sluggish service.
