The reason why it is cheap is because the price given by the booking website is different.
It is recommended to book tickets online (choose the lowest discount ticket). Although there are many complaints that online booking is deceptive and various industries have irregular operations, not all booking websites have a bad reputation. Otherwise, no one will book tickets online. After finding the special ticket information, if it's a website you haven't bought, I suggest you search Baidu for the word "* * online deception" and then look at the comments of netizens on the website. If you don't find such a word, or some netizens have successfully booked tickets on this website. That means the website should be reliable and can book tickets.
After the payment is successful, let the website mark () for you. You can check the flight information on (Xintianyou). If you find it, congratulations, you have successfully purchased the ticket. You can relax 99%. . I have seen some netizens cancel flights on the Internet. This is the behavior of airlines. You can ask for a refund, and the funds are still safe. In order not to affect your normal itinerary, please check your ticket a few days in advance. I have booked tickets many times, and this has never happened. Finally, I want to talk about it, because many tickets booked online are special fares. Websites generally require insurance. Be sure to let the website tell you the policy number, and then you can go to the insurance company's website or call, otherwise there may be no protection. Don't be afraid of this trouble.
