Perhaps you should try some spelling variations:
thanh tai » thanh hai, thanh toan, thanh san
hieu van » hieu va, thien van, lieu va
van cam » van nam, van lam, van cau
xuc ban » duc ban, cuc ban, quoc ban
cua tre » cua te, cuu tre, cua triet
pu xac » su xac
xac ky » cac ky, sac ky, bac ky
x hoi » o hoi, x ho, 5 hoi

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: pu xac ky nang ((x hoi) OR (xa hoi)). hieu van cam xuc ban ((thanh tai) or (doanh tai)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: pu xac ky nang ((x hoi) OR (xa hoi)). hieu van cam xuc ban ((thanh tai) OR (doanh tai)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "pu xac ky nang ((x hoi) OR (xa hoi)). hieu van cam xuc ban ((thanh tai) or (doanh tai)) cua tre".
• Adding a wildcard symbol may retrieve word variants: pu xac ky nang ((x hoi) OR (xa hoi)). hieu van cam xuc ban ((thanh tai) or (doanh tai)) cua tre*.
