Zhang’s another advantage is his good English proficiency. In January this year, Saffa Riffat, the president of International Renewable Energy Association, visited our school and Zhang worked as the translator for Professor Saffa Riffat. In my opinion Zhang has the vision of an international student and could think of some issues from the global perspective which is very valuable for an undergraduate student in the modern society. For this point I am very supportive of him and hope that he could have more opportunities to carry out international studies and exchanges. At present I am guiding him to write a paper which is to be published in the international renewable energy conference of this year.
