QDII (Qualified Financial Institutional Investors) is a mechanism for local investors to invest overseas in countries (regions) where the capital account is not fully open. Investors can only buy and sell through this mechanism, so that the state can supervise the flow and scale of funds. QDII can set up a closed-end fund (that is, after the fund expires, the principal and return can be recovered in one lump sum, and the period can not be traded), and set the upper limit of the term and investment amount for investors to subscribe, and the fund manager is responsible for the investment. The above forms allow SAFE to supervise the flow of funds and ensure the return of funds to the country.

the ConsumerPriceIndex, abbreviated as CPI in English, is an indicator reflecting the price changes of products and services related to residents' lives, and is usually used as an important indicator to observe the level of inflation. If the consumer price index rises too much, it shows that inflation has become an unstable factor in the economy, and the central bank will risk tightening monetary and fiscal policies, which will lead to uncertain economic prospects. Therefore, the excessive increase of the index is often not welcomed by the market. For example, in the past 12 months, the consumer price index rose by 2.3%, which means that the cost of living rose by 2.3% on average compared with 12 months ago. When the cost of living goes up, the value of your money goes down. In other words, a 1 yuan banknote received a year ago can only buy goods and services worth 97.7 yuan today. Generally speaking, when CPI> 3% increase is called INFLATION, which means inflation; And when CPI> When the growth rate is 5%, we call it SERIES INFLATION, which means serious inflation.
