Note that in this case, you either need a literal argument {{}} or to explicitly escape the # character as in:
= History of Tiananmen Square
to avoid the creation of an insane topic link with a single word.
Also note that Wikipedia subsections are not completely stable, so generally you would rather want to link to a permalink with a full URL as in:
= Artificial general intelligence
Note that in this case escaping the # is not necessary because it is part of the insane link that starts at https://.
