Hi & welcome to the forum.

Chinese are considered a solitary species now, these two are still young so they may be happy to stay together for a while yet. Females do tend to be more territorial than males so the chances are they will want their own space as they mature & will need to be separated.
You could keep them together for a now & see how they go closely monitoring them for any signs of falling out or you could separate them straight away if you feel happier about doing it that way, it may take them a while to adjust but they will be fine living alone.
