Two times traveled to Paris, first time I lost everything of me include Passport, ID card, bank card, money in cash. Even worse that day was my 21 years old birthday.
Second time I found some interesting chinese friends traveled with me. Some of them have studied in Paris for many years. So they took me around city and visited some special places where a tourist can never find.
It’s a video in Line 6 subway train which passed by eiffel tower.
