Humanitarian visa after overstay

I went to China on a one month business M, overstayed it for about 5 months due to an agent's receipt. So, I reported myself to the local police, was taken to immigration, paid 10.000rmb fine and was given 2 month humanitarian visa. I left China immediately. I want yo go to China again, but i'm scared i maybe sent back at the airport upon arrival. Can I be stamped in? Help me, please.
