You cannot add section _ to Yuekang code.

That means you added it wrong.

The shortcut setting method of Yuekang code is relatively simple, just create a new shortcut instruction, add an operation, search and select "Open URL", paste the URL link prepared in advance, and finally name the shortcut instruction. However, you can also use the shortcut command link to directly copy the health codes that others have created (sorted) and open Add in Safari browser.
