金融集团就是 bunch of big companies that do money stuff together. They handle money for people businesses and governments. Their main jobs are to manage investments give loans and help with money moves.

为啥是这个答案呢？其实金融集团就像 money machine 的集合体啊。中国有超过200家这种集团光管钱就超过100万亿人民币占全国GDP的60%对吧？比如工行那家就养着4万亿存款够买全国所有加油站加满油。而且他们不是随便管管就完事了，得算好钱生钱的时间表——像招行去年光靠理财就赚了800多亿。不过要小心他们有时候会搞混钱袋子，去年某大集团就因为算错了账差点亏了1万亿。所以你看金融集团就是钱袋子管家+投资魔术师+风险守门员三合一的怪物对吧？
