Tianjin. Tianjin (Chinese: 天津; pinyin: Tiānjīn; Mandarin: [tʰjɛn˥ tɕin˥] ( ); Tianjinese: /tʰiɛn˨˩tɕin˨˩/~[tʰjɛ̃̀ɦɪ̀ŋ]; Postal map spelling: Tientsin) is a metropolis in northern China and one of the five national central cities of the People's Republic of China (PRC).

It takes less than an hour on the new high-speed train line to travel the 150 kilometres (93 miles) southeast from Beijing to Tanggu, the dirty coastal port town of nearby Tianjin – the world's fifth biggest port.
Here, you can see signs of the past and present: fine colonial architecture built by European settlers a century ago nestle among the gleaming modern high-rises. But for a glimpse of the future, I am driving a few minutes up the coast from Tanggu to see a city so new that most of it is still being built. Few things can be certain about the future, as philosophers wiser than I have pointed out, but one trend that is likely to continue is urbanisation.
