As long as regular university graduates have a degree certificate, foreign schools can't help but admit it. You can apply for a master's degree and a doctor's degree after graduation, which is similar to that in China, but if the graduate students you are studying don't necessarily recognize your research and professional background, you need to talk to the school or professor, so you can't generalize.
Your friend's parents mean "stability". I can't get out and I won't have nothing to do. You can also study in China. But doing so will be problematic. The biggest problem is your time. First of all, you need at least one year to take the postgraduate entrance examination and learn some useless things. Then you don't go to graduate school. This prime time is wasted. In addition, you can't go out immediately after graduate school, which takes about a year. During this period, foreign schools may not necessarily recognize it, and they may not necessarily waste it. In addition, you are not on vacation, and you still have a lot of work to do, which will inevitably affect your language learning and application affairs, and ultimately affect the success rate of your application.
Another problem is the relationship with the professor. Because your graduate school occupies the position of study, you went abroad before you finished your studies, which brought trouble to the professor, and then you had to write a recommendation letter from the professor. Which professor would be happy? But it's generally okay. It's no problem to talk to the professor.
