Citigroup: 1955, Citibank of new york merged with the First Bank of new york and changed its name to the First National City Bank of new york; 1962, renamed First National City Bank; 1967, renamed Citigroup, headquartered in new york. 1998 merged with Traveler Group to form Citigroup, becoming the largest financial services company in the world.

When Citibank first opened a branch near the Bund in Shanghai, there were always many American flags hanging in front of the door. Shanghainese think "Citibank" is too awkward to read in English, but everyone knows that Citibank is a bank of America, and the American flag is like a blue and red rag. Over time, Shanghainese simply called Citibank "Citibank", and its Chinese name was accepted by Citibank, which has been used ever since.

Citigroup is the first financial group in the United States that integrates commercial banks, investment banks, insurance, mutual funds, securities trading and other financial services. The combined Citigroup has total assets of $700 billion and net income of $50 billion. It has 654.38 billion customers in 654.38+000 countries and issues about 60 million credit cards.

Citigroup also has a special investment bank, the full name of which is "Oriental Citigroup Securities Co., Ltd.". Because foreign banks are not allowed to enter China alone, it is in the name of orient securities, but it has nothing to do with orient securities. There are representatives of Citigroup in the United States.
