I appreciate your detailed request, but I need to be straightforward: the provided sources do not contain sufficient material to write the guide you've asked for. Here's what's missing from the sources: **On nightlife venues:** The Wikivoyage source has a "== Drink ==" section header but no actual content beneath it. There are no named bars, clubs, beer halls, ruin bars, or live music venues listed anywhere in the sources. **On districts/streets for going out:** The sources mention Pingcheng and Yungang as urban districts, and reference a few historical sites (Huayan Monastery, Shanhua Temple, Nine-Dragon Wall), but provide no information about which neighborhoods are lively in the evenings or what streets locals frequent for nightlife. **On how evenings unfold:** There is no source material describing the pace, timing, or rhythm of an evening out in Datong. **On opening hours and venue types:** No specific information about bars, clubs, cafes, or when establishments close. **On festivals:** The dated events list includes Spirit Festival (August), Mid-Autumn Festival (September), and National Day (October), but contains no details about how these are celebrated or what they mean for visitors to the city's nightlife scene. To write an honest, source-grounded guide to going out in Datong, I would need sources that actually describe the city's drinking, dining, and entertainment districts, specific venues, and social rhythms. Without those, any guide I wrote would either be generic or would require me to invent details—both violations of your (correct) requirement that facts be non-negotiable. Would you be able to provide sources with information about Datong's nightlife, dining, and entertainment culture?
