There are many opportunities for doctoral students in 2.985 colleges to go abroad, and the competition is not very fierce. The required conditions are: PETS-5, IELTS or TOEFL score up to standard, some preliminary research results, an invitation letter from a foreign party, and then the tutor agrees, the college recommends, the graduate school approves, and the National Scholarship Fund Committee approves.
PhDs should be difficult to take, and of course they are divided into different people. If you have excellent conditions, teachers should like to recruit.
