The most visited area is the one within the city walls. In the style of the Forbidden City of Beijing, Xian has about 14 kilometers of surrounding wall The old city. You can take a walk through it - which will take you about 3 hours going quietly and enjoying the scenery - or rent a bicycle for 40 Yuan.
When you have been a little hungry I recommend you walk around the Muslim Quarter, located just behind the Drum Tower. A multitude of street stalls are full of skewers, cakes, nuts, sweets, noodles ... In short, a mixture of very intense flavors and smells that you have to try without asking too much about the origin of the meat or the hygiene of the stalls. If your stomach is already bombproof, great, if not, then you may have to go to the bathroom more often than usual for a few days, but nothing more.
We walked along the wall of the South Gate to the East - where we met our friends Kan Hi, from South Korea, and Li Xie Bo, a Chinese student - went to eat fried cakes stuffed with minced meat and ginger - for 5Y - and we saw from outside the Great Mosque, the Bell Tower and that of the Drum.
The wall was full of color and ornaments due to the proximity of the main Chinese holiday: the Chinese New Year. I recommend you stay close at night to see the beautiful lighting of all the ornaments.
To enter any point of interest you will have to pay. This is a habit that is widespread throughout China, wherever you are.
Then we dedicate ourselves to wandering through the streets of downtown, simply contemplating the stressful sway of people and cars, entering a supermarket - a hidden vice that we both have: love for supermarkets in all countries - and walking through a jumble sale of brushes, jade, fans, wooden items and several other things, which is located right next to the south entrance to the wall.
The truth is that we are still in a point of cultural shock so intense that simply walking through the city and contemplating its people, hearing their unintelligible conversations and observing their habits are enough for us to consider a day as well used.
You lose in the streets impregnated with the history of the ancient capital of China!
