Homeward trend in judicial cases relating to Taiwan, which is to some extent reasonable and has some legal basis, is the phenomenon that the judge applies the law of mainland China directly without the guidance of conflict rules. However, it does harm to the exchanges between people from mainland and Taiwan, if homeward trend is not properly controlled. Measures such as improving the reasoning of verdicts, analogy of international uniform substantive law, should be taken to confine the phenomenon of homeward trend.
