There is no way to pass the scores of Peking University. First, after the exam, write a letter of recommendation in English. If there is a reply (mainly depending on the background of your recommendation letter), he will inform you of the interview, written test and comprehensive quality question and answer in the mainland. It's over. Congratulations. You should study English in mainland China for two years first. If you can keep up with the progress, you can go to HKU in two years.
