Practical tips
Best time
China is continental, with very different climates by region. In general, spring and autumn are the most pleasant seasons in the big cities; check the climate of the specific region you plan to visit.
Languages
Mandarin is the official language; there are many regional languages and dialects, such as Cantonese in the south. Outside tourism and business circles English is limited, and Portuguese is rare. A translation app downloaded for offline use helps a lot.
Etiquette
Discreet greetings, respect for elders and patience with queues and paperwork take you far. Note your accommodation address in Chinese characters to show taxi drivers. The rest of the practical guide is in preparation.
What to see & culture
Places
The Great Wall; the Forbidden City and the Temple of Heaven in Beijing; the Terracotta Army in Xian; the Bund and Pudong skyline in Shanghai; the karst peaks of Guilin and the Li River; the pandas of Chengdu.
Culture
One of the world's oldest continuous civilisations: calligraphy, tea, classical gardens, Peking opera and a technological modernity living alongside millennia of history. Each region has its own identity.
Food
Very distinct regional cuisines: Peking duck, Cantonese dim sum, Sichuan heat with its hotpot, the noodles of the northwest. Eating is the centre of social life; sharing dishes is the norm.
