Saying he should bid 3NT misses the point of the question IMO, which is that if 3♣ is checking back it doesn't promise 4 spades as the OP seems to believe, it can be (and usually is) based on 5 hearts checking back for a 3 card fit.
It may be a language issue, but I interpreted "what bid south?" to mean "what bid south?" which is the question I and others provided an answer for.
I, personally, hoped that my failure to address what 3
♣ should be would imply that 3
♣ is not what I think OP should bid, and therefore shouldn't be a concern. If OP wanted to know what 3
♣ should mean, it seems more effective to not give a hand that shouldn't bid 3
♣, or to use the handy search feature to find other threads that deal with the topic.
