dey should seal the company and force them to compensate the family with millions of naira and the man should be hang because no nigeria citizen will kill a china citizen in china and allow to be alive upto a week even other nigerians there will suffer the same sin that one nigeria committed for that the chins should be hang with out delay because if it were in china they will not spare the nigeria. for that reason that company should be sealed so that others will learn lesson. we should lean how to be one in a situation like this so that we have respect as a NIGERIAN,
