Tips
history
Founded in 1908 in the late Qing dynasty, 交通银行 (BoCom) is one of the oldest modern banks in China. It is now one of the 'Big Five' state-owned commercial banks, along with ICBC, CCB, ABC, and Bank of China.
usage
The character 行 is read háng (not xíng) when it means 'bank' or 'firm'. 银行 = yínháng (bank).
