Chinese phrase: the meaning of Huitong

I saw the word "Shanghai Huitong Bank" in the name of a bank. As the name implies, it is the collection and circulation of the bank's finance, currency and expenditure, which is the entry and exit of banknotes. Of course, it hopes to deposit all the money in the world and then lend it, so as to realize the infinite accumulation and expansion of its capital in the process, thus charging the maximum interest!
