Reading the question again, you (Yue Wu) are echoing the function's
return value (the empty string) immediately after the function returns,
thus erasing what was displayed by the function itself.
You may prefer to invoke the function (still from Insert mode) by
<C-O>:call Hi()<CR>
which does not dosplay the return value.
Best regards,
Tony.
