Hi! I’m Cambodian and now I working in mainland China and I will go back to Cambodia on April.

My working permitted visa here will expire on 11 of April. When I come back , I want to apply for tourist visa for visiting in China with my parents and brother. But I herd that for Cambodian women around 18-35 year old that not yet get married is not allowed to get that entry permit. Is that true? And can I apply for it?
