The intense and busy training and study are over. First of all, thank the tutor for guiding our study. In the extraordinary sixty days, online training has brought us together. Although it is the first time we meet, we share joys and sorrows from strangers to acquaintances and from acquaintances to acquaintances! Although we've never met, we are connected. Sixty days and nights, after ten times of tempering, for a common goal, we go hand in hand, bitter and sweet, tired and loving. Maybe you are physically and mentally exhausted, but I believe you are full of energy and your thoughts are shining.

Whenever I log on to the teaching platform, whenever I witness the communication and learning track of teachers, whenever I communicate with teachers in silent language, whenever I read every discussion post with relish, my heart will always be excited. I am happy to be your learning partner and work together with you. I sincerely admire those teachers who can overcome the difficulties brought by work, family and study, work nonstop until late at night, and meet the learning and challenges with full swing enthusiasm; Teachers' tireless learning spirit, I see that the future of education will be better!

In the days that are coming to an end, complex emotions come to mind. I sincerely thank the teaching platform of Peking University for bringing us together! The parting bell has rung, but my heart sings "I don't want to say goodbye …" Now, even though there are thousands of words, I can't express my feelings at this moment. I hope that "however, as long as China keeps our friendship, heaven will remain our neighbor", not to mention that we still have a trace of friendship.

Parting is sweet sadness and the beginning of missing; Parting is equally beautiful, because it is a prelude to gathering. Don't cry because of sadness, spread your smile, and let us keep this beautiful memory in our hearts forever. Years are like songs, wishing each other a better tomorrow! Teachers, may our friendship last forever!
