The Blue Mosque must be the best in the world. In May, on International Labor Day, I did not expect to go to the queue so early in the morning. I lined up with friends and I went to the next place to take a few shots. Suddenly, I awakened by the melodious chanting, this really meant that we were in an Islamic country. The place where we stood in a line is similar to the Shanghai World Expo. The back-shaped railings are in good order. After entering, you can receive long scarf shawls.
