2. Take the SOOPAT website as an example (you can find it directly from Baidu SOOPAT, and you don't need to post a URL here). Go to SOOPAT's homepage and click on the "Table Search" column.

3. Enter "1324636" or "120 1752" in the column of "AnnouncementNo." and click "SOOPAT Search".

4. If you need to download the full text, you need to register.
