From Jan to Mar, 2017, I was happy to have an exchange study in Helmholtz-Zentrum Berlin für Materialien und Energie. During my stay in Germany, German culture and customs as well as German precise scientific attitude impressed me a lot.
Helmholtz-Zentrum Berlin is located in Wannsee, a beautiful lake in Berlin.The smell of Christmas is still there when I arrived. Snow and magnificent churches add radiance to each other.

Research institutions in German have a more rigorous time mechanism, limited working hours promote higher efficiency. I really appreciate their pursuit of efficiency and their attitude towards science.
  In my spare time, I also explored Germany by visiting magnificent Brandenburg Gate, the legendary Berlin Wall, mysterious museum island and so on.

The exchange study in Germany has made my vision of research even more broad. I want to show my gratefulness to Prof. Matthias Ballauff and Professor Yan.Luu for their invitation and guidance, and thanks to Dr. Zdravko Kochovski for his kindness help in scientific project!
