No one has traveled far since I was a child, so I just dare not go out alone. Should I exercise?

Yes, be bold and exercise yourself. Try to grow up slowly and learn to live independently. Loulou can choose to follow a tour group when going out alone for the first time. If you feel that you don't want to play with so many people, you can travel alone and choose the counties and cities in the province for two or three days. When you are familiar with it, consider going to a distant place and traveling to your favorite place.
