South · 2 nights · November to March. Summer is long, wet, and hot.
Guangzhou
The city that invented the long breakfast, and still takes it more seriously than sightseeing.

Morning tea, a river capital
Guangzhou is a food city that happens to have a skyline. The correct first appointment is dim sum while the steamers are still energetic, ideally before nine. Shamian Island is a short, shady walk of colonial arcades when you want architecture without a mission. The Canton Tower and Pearl River cruise are night decorations, pleasant once. The heat and the pace are real; plan indoors at midday and a second round of tea rather than a monument march. Cantonese cooking here is cleaner and less sweet than the export version many travelers expect.
See
A serious dim sum house 早茶
This is the sight. Go early. Point at carts or order from a sheet, and stop before you are proving a point.
Shamian 沙面
A small island of shaded streets and old trading houses. An hour, not a day.
Chen Clan Ancestral Hall 陈家祠
Carved wood and ceramic ridges. The best indoor architecture stop in the city.
Pearl River at night 珠江
A short ferry or a walk on the promenade. You do not need the loudest cruise.
Eat
Har gow and siu mai
The test of a kitchen. Shrimp should be sweet, wrappers thin, and the tea hot enough to reset your palate.
Rice noodle rolls
Silky sheets, often with shrimp or beef. Breakfast, or whenever the steamer is still patient.
Claypot rice
Evening food. Wait for the crust. Soy chicken or cured meat are the classic lids.
