There are many kinds of emails that the teacher replied to you just after the postgraduate entrance examination. I think replying to you as a teacher is just to cope. The teacher who really wants you will say, can you give me a copy of your academic performance and resume? I am interested in you by answering you like this. You can go to her directly and tell her face to face that a really extravagant teacher has no shelf. If she is willing to pick you up, she will readily promise you.
Finally, I wish you success in your research ~ ~
