did she need a passport and visa

Nawal, I don't know whether you and her father decide her nationality. Since her dad is a Chinese, she can be a Chinese. If so, you should apply for a Chinese passport for her and then apply for an Algerian visa. If you choose to let her be an Algerian, you should acquire an Algerian passport for your embassy in China. Meanwhile, you should apply for a Chinese visa for her. Otherwise, you can't take her out of China.
