Today we will learn about the word, 财 (cai).
财 refers to wealth.
It is commonly used together with other words such as
财经 (cai jin) which refers to finance
理财 (li cai) which refers to finance management.
An interesting point about the the word is the left character, 贝 (bei), which is commonly found in words that use to describe money. 贝 actually means shell (yes, like those you will find by the beach). However, this is because back in the olden days, shells were used as trade goods which indicate some monetary value and thus has been continued to be used to represent wealth.
