2, Baidu Nuomi is a Baidu a product; principal gold merchants and silver merchants are Baidu through-train products; their **** the same point is mainly for companies with stores.
3, Baidu products through train is for Baidu mobile advertising and promotion, is to pay, at the beginning of the time is the local bronze merchants, when your daily consumption is relatively large at the same time continued for about 1 month's time, it will be upgraded to the local silver merchants (which in the signing of the contract before you must ask the Baidu customer service), and then continued for a period of time will be upgraded to the local gold service providers.
Bronze, silver, gold, this is actually the use of the customer's good sense of reasoning, think the gold must be the most powerful, professional ability and level of service should also be the most powerful, and then again local, will go to consult this company.
In fact, no, the local gold medal service is based on your consumption accumulation, later will be automatically upgraded up, so no big deal. You still need to visit them directly, interview them, and learn more about them.
