Autumn (September–October) is crisp and clear with golden leaves; winter (December–February) brings snow and the cheapest quiet visits. Summer is short but warm.

Two days cover the palace, mansion, Beiling and Middle Street; add a third for Qipanshan or a museum.
No — as an industrial provincial capital it is inexpensive for eating, staying and taking taxis.
Hearty northeastern portions: generous stews, dumplings, smoked pork and strong flavours; western options are also common.
Taoxian Airport (SHE) is about 22 km out with airport buses; Shenyang Station and Shenyang North are major rail hubs, and metro lines 1 and 2 link the sights.
