Is it enough to have a PhD and some degree of study abroad experience to qualify a person as a mentor? Even if I don't deserve a master's degree. So ask yourself, are they really qualified? It made me feel miserable, sick, numb and deeply disappointed.
Do not have that strength, do not advertise strong, should learn from the excellent system, excellent environment, there is always nothing wrong with learning from each other, blindly belittling will only be backbiting.

It doesn't matter if no one pays attention to you, or if your skills are not as good as others. You should try to calm down and do what you need to do, instead of letting worries and anxieties destroy your limited passion and determination. Your heart may be broken, but your hands should not stop. You should keep doing what you need to do and continue moving forward even when you are on the verge of collapse. This is the true character of an adult.
无人问津也好，技不如人也罢，你都要试着安静下来，去做自己该做的事情，而不是让烦恼和焦虑，毁掉你本就不多的热情和定力。心可以碎，手不能停，该干什么干什么，在崩溃中继续前行，这才是一个成年人的素养。

I don't play the guitars, but i love music,favorite.
To be a singer is my dreaming.
Just going international. and so on,
I'm really likes Chinese and English.
I'm not like playing basketball.
Because i am too short.
And I'm don't be a driver,
Because i am depressedof the world.
But stay happiness is my world.
