However, whether to adopt "names with the same suffix" is also controversial. On the one hand, some people think that this will cause confusion and unclear characteristics between brothers and sisters, so they do not advocate it. On the other hand, some people think that such similarity of names can help to maintain family relations and the intimacy between brothers and sisters in some cases.
Therefore, whether the endings of two brothers' names are the same should be decided according to personal circumstances and preferences. Whether or not to use the same surname, the key is to respect the decisions of individuals and families and avoid using names that are too personalized or difficult to pronounce.
