Beijing was special for me because of its contrast to Erlangen. Erlangen is unique because it is a compact and slower-paced city; it is an ideal location for a student to focus on their studies without many distractions.
Comparatively, in Beijing it is a vast, stimulating and arguably exhausting city. A place I felt I did not have enough time during the day because there were a lot of activities to do. For example, a typical day at Peking University would require me to manage mandatory, elective and language classes, extra-curriculars, work, and personal downtime.
Finding a balance between these activities is important because I believe participating in different activities sparks creativity and motivation.
