Plus, the clue is ambiguous; it could be attributed to the Lizardman.

That's what, in my opinion, speaks against the idea that it's a clue pointing to Nera (I'm not defending her, just to be clear). I think the GM wouldn't give a clue that quite clearly points to another player. Although, who knows. In any case, we're unlikely to hang anyone. The Townies don't want to take responsibility for executing a possible Town member, and the Mafia don't want to reveal themselves by executing a Town member or a Mana user.

But why not? The city is from China, so you can search Google for "Chinese poets," "Chinese artists," or "Chinese... something else."

The problem is that it's quite difficult to find information about this poet. Besides, the information about him seems to be only in English.

And I'm not saying it's convincing. "InGen" and "GenIn" are different words, so the clues are nonsensical. Both yours and mine.

Maybe, but as I already wrote, in my opinion, the option I suggested is better than the options suggested by other players.
