The following steps can be used to judge whether the Youth Foundation will attend the meeting:

1. Open a browser, enter "National Natural Science Foundation of China" in the search box, and click "Project Application and Inquiry" in official website.

2. In the jumped page, click "Applicant Login" and select an area, such as "Anonymous Login".

3. Enter the account number, such as user name, click "Login" and select "Scientific Research Project" on the login page.

4. On the scientific research project page, enter the project code, name and verification code, and click "Query".

5. In the query results, you can view the project status. If the status shows "In Progress", it means that the project has been launched. If the status is "Closed", it means that the project has ended. If the status is cancelled, it means that the project has been cancelled.

It should be noted that the project inquiry system of the National Natural Science Foundation of China only provides login inquiry function for applicants who have registered and submitted projects. If you haven't registered, you won't be able to check whether anyone is participating in your project. In addition, the project status will be updated and adjusted according to the actual situation, so patience and attention are needed.
