1. Promotion: The nine-yuan genuine card is a promotion activity, which is launched by some travel websites or air ticket agents. This card can be used to buy air tickets, hotels, tourism products, etc. And the price is much cheaper than the normal price.

2. Special channels: There are many conditions and restrictions on the use of the nine-yuan genuine card, such as the use time, the scope of use and the number of users. These restrictions make the nine-yuan genuine card can only be used in a specific channel or within a specific time, thus reducing competition and supply and lowering air ticket prices.
