It is a great honor for me to be given the  Kato Asao International Scholarship as an international student from Asia.  I would like to thank Professor Ma, Assistant Professor Tian and all other members in my lab for the support.  I am young and inexperienced but I will keep up the hard work on my research. Now that we are in the middle of COVID19, it is difficult to study face to face but I hope that we can help and encourage each other and do the best we can.
