All of them are found online. There are quite a few common bidding websites now, but because each one focuses on different information aspects, it still depends on your information needs, or choose a comprehensive website, such as China Bidding and Purchasing Navigation Network. There are many free bidding announcements on the home page of China Bidding and Purchasing Navigation Network, where you can find the bidding announcements of school canteens and supermarkets you need. If you want to find the bidding information without spending money, it is ok, but it is a bit troublesome. There is no official website dedicated to publishing bidding information in China. After all, there are more monks than meat. When you see the information, your competitors are already actively contacting. You can try various government websites to see if there is any update, and keep an eye on it. In addition, bonus hunter is a reliable bidding information website. In order to let users use the pages with free announcements, you can find the pages with free announcements, and the information inside is public enough for you to read. Internet crawler technology is adopted, and the bidding information covers all parts of the country, mainly from government websites and industry websites. You can view the bidding notice, change announcement, question-and-answer clarification, bid-winning announcement, termination announcement, inquiry purchase, etc., and support users to input keywords, filter areas and select bidding information suitable for them to support bidding subscription, that is, users customize keywords, areas and information types, so that the software will automatically push information to your mobile phone to ensure that no bids are missed. It is also important to know the competitors' situation in detail in bidding work. The software supports checking the qualification information and historical winning performance of competitors' enterprises and builders. The basic information of the builder also has the function of checking the project information, including the projects to be built, government projects, commercial projects, etc., which supports the project focus, and the information in this aspect is of higher value; At present, the traditional bidding mode has been gradually eliminated, and more and more electronic bidding platforms have completely replaced them. Bidding is an important procurement method between government units and enterprises, and the fully open mode is more conducive to the government's supervision and management of the bidding process. The electronic bidding platform can not only collect all the information and data of the bidding unit, but also be more convenient for bidding enterprises. A more open and transparent bidding process can also greatly avoid the loss of state assets caused by corruption. At present, bidding websites are divided into three categories, for your reference: government procurement website and public resource trading center are usually official websites of government nature, which are generally the first publishers of bidding, and the unified procurement trading platform that the provinces are responsible for, which is absolutely authoritative and generally free of charge, but it is troublesome to find information and the information is relatively scattered. The establishment of such websites makes bidding no longer limited by space and region, and also helps purchasing units to choose better cooperative enterprises. I have carefully collected and sorted out the bidding websites of 22 provinces, 5 autonomous regions and 4 municipalities directly under the Central Government. I don't need to talk nonsense and put links directly, so you can take them yourself.

I only listed some purchasing bidding websites of well-known large enterprises to use according to my own needs.
