Super fun! I loved being in Shanghai and meeting different people. The people were pretty friendly and the efficiency in the city was unbelievable. I could go out the dorm without cash or my wallet. Everything I needed was on my phone. It lessened my traveling weight, plus it was so easy to book high-speed train tickets and plane tickets. I could travel to close-by provinces within 3 hrs and come back within the day. It was awesome. I loved yellow mountain and Beijing. Both were different experiences but very enjoyable.
