:::::...So I looked up [], and following those principles there seems to be no reason to delete ANY of the weird redirects. Which brings us back to your original suggestion about WHERE to redirect. Here's all I really have to say about that: As long as ANY of the spellings of "taiji" (including Wade-Giles spellings) redirect to T'ai chi ch'uan, that article must have a hatnote pointing back to Taiji  which I will now add.
