I have been to China twice. I experienced a culture shock in China. I couldn't throw the toiletpaper into the toilet. I was surprised at first, because in Japan, we can do it. In addition, This is not a culture shock, but I had a thing that surprised me in Korea. I couldn't pay in cash at Starbucks in Korea. It only took a credit card or Starbucks card, so I couldn't buy a frappucino there. I thought that Korea is growing more the cashless system than in Japan. I think these cultural difference are interesting. I would like to visit more countries and learn more about foreign culture and life.
