Start your trip by visiting the Terracotta Army, one of the most iconic archaeological sites in the world. Marvel at the thousands of life-sized clay soldiers and horses that were buried with China's first emperor, Qin Shi Huang. Afterward, head to the ancient city walls of Xi'an and take a leisurely bike ride or walk along the 14-kilometer-long fortification. Enjoy panoramic views of the city and its surroundings. In the evening, visit the Muslim Quarter, a bustling area filled with food stalls and shops selling traditional crafts and souvenirs. Try some delicious local street food like lamb skewers and roujiamo (Chinese hamburger).
