I'm from Bangladesh.I have a question regarding entering and leaving china.I am going to take admission in a chinese university.That means I will be given X visa,which is student visa.I have a desire of visiting my country frequently to see my family.Although I will be studying in china,I want to come to Bangladesh whenever the pressure of study is less. May be,I will try to come to Bangladesh every 2 months later to stay with my my family for 7 to 8 days.Now my question is,will this be possible with 'x' visa?I mean can I enter and exit china so many times while having a student visa and Bangladeshi passport?Does student visa of china have multiple entry permission?
