Chongzuo sits in southwestern Guangxi on the Vietnamese border and is the city most travellers pass through without stopping — the Detian Waterfall to its west and Nanning to its east tend to absorb all the attention. This is a mistake of sorts, because the area around Chongzuo has two things worth going out of the way for: the Huashan cliff murals, a UNESCO World Heritage Site along the Zuojiang River, and the Chongzuo Ecology Park, one of the better places in China to see the white-headed leaf monkey, a primate endemic to this corner of Guangxi that is genuinely endangered and genuinely striking.
The Huashan murals cover a massive cliff face above the Zuojiang River — a two-thousand-year-old sequence of red ochre figures, animals, and ritual images attributed to the ancient Luo Yue people, ancestors of the modern Zhuang. The scale is impressive and the setting, river bend below sheer limestone, is beautiful. Reaching them involves a boat trip along the river that is worthwhile in its own right. The Friendship Pass (Youyiguan) on the Vietnamese border is a well-preserved fortified gateway that has seen several thousand years of trade, diplomacy, and war between China and Vietnam, and the hill surrounding it has views into both countries.
Chongzuo is a stronghold of Zhuang culture and the Sanyuesan festival in the third lunar month brings traditional singing competitions, bamboo dances, and the kind of cross-border festivity that the official border checkpoints twenty kilometres south would never suggest is possible. The city is also the self-declared sugar capital of China, surrounded by sugar-cane fields that give the landscape a particular flatness between the karst hills.
The city is 90 minutes from Nanning by road or high-speed rail, making it feasible as a base for the southwestern corner of Guangxi rather than just a waypoint.
