शियान आधा दिन: 4 घंटे की ज़रूरी यात्रा

Start at the Bell Tower (钟楼, Zhōnglóu) — the geographic and symbolic center of Xi'an, where the four main streets of the old city meet under a Ming-dynasty wooden tower. You don't need to climb it (¥30, 30 min if you do); the photos from the pedestrian underpass are the shot everyone takes, and they're free. This is your orientation point — everything on this half-day walk radiates from here.

The Muslim Quarter (回民街 / 回坊, Huífāng) is Xi'an's food soul and the single best use of two hours in the city. Skip the souvenir-choked main strip (Beiyuanmen) after the first 50 meters and duck into the side lanes — Dapiyuan (大皮院) and the alleys behind — where the real eating happens. Grab a roujiamo (肉夹馍, the Xi'an pork "burger"), a bowl of biang biang noodles, and a persimmon cake from a street cart; ¥30–50 buys a feast. If you have time, peek into the Great Mosque (清真大寺, ¥25, Chinese-temple courtyards unlike any mosque you've seen).

End on the City Wall (城墙, Chéngqiáng) at golden hour — enter at the South Gate (永宁门, Yǒngníngmén), climb the ramparts, and watch the old city light up as the sun drops behind the rooftops. ¥54 admission; you can rent a bike (¥45/3h) and ride a stretch of the 13.7 km circuit, or just walk the ramparts for 30 minutes and take in the view. The wall stays open until 22:00 in season, so there's no rush — this is the moment the day clicks into place. Metro Line 2 (Yongningmen station) takes you home from the gate.
