1. The borrower is required to repay the principal and interest on a monthly basis. In this way, the amount to be repaid each month is very small and the repayment pressure is also small. The lender can receive the repayment on a monthly basis with little risk. 2. Credit audit introduces socialization factors. That is, the borrower's ID card, account book, marriage certificate, academic certificate, etc. can all increase personal credit scores, but these data do not need to be provided with the original, and their authenticity is difficult to be effectively guaranteed. Therefore, the auction believes that the online community and users' online circle of friends are also one of the important parts of their credit rating system. The more friends and members' friends in the inner circle of the website, the higher the number of times individuals borrow and lend, and the higher the credit rating. In this way, the network activity and the user's personal identity, financial ability, bank credit, etc. together form a complete set of evaluation system. The unsecured and unsecured mode has only credit requirements for the borrower but no mortgage, and does not assume guarantee responsibility for the lender. The lender and the borrower trade on their own, and the auction only exists as a witness and trading platform. Therefore, in fact, this form is relatively risky for lenders. However, the winning interest rate for auction is often above 15%, which is still a great temptation for lenders. Therefore, investment in auction and loan has higher risks and higher returns. Because the transaction is concluded in the form of competitive bidding and both parties to the transaction are free to trade, the auction and loan belong to pure intermediary P2P. The auction will blacklist the borrower who fails to repay the loan within the time limit and make it public, but it will not compensate the lender for the economic losses. The auction will only refund the lender's handling fee, so the potential risks of fund recovery can only be borne by the lender itself.

The following procedure is to use the state mode to improve the light. When it comes to encapsulation, the behavior of the encapsulated object is generally preferred over the state of the object. But the opposite is true in state mode, The key to the state mode is to encapsulate each state of the thing into a separate class, and the behaviors related to this state are encapsulated inside this class, so when button is pressed, only the request needs to be delegated to the current state object in the context, and the state object will be responsible for rendering its own behaviors. At the same time, the state switching rules can be distributed in the state classes in advance, thus effectively eliminating a large number of conditional branch statements that originally existed.
