Perhaps you should try some spelling variations:
thien van » thi van
van pham » san pham, van phan, van phat
hanh vai » hanh vi, hanh tai, hanh van
hanh va » hang va, hanh vi
duc ban » duc tan, duc van, dua ban
cua tre » cua te, cuu tre, cua triet
nang xa » nang x, lang xa, nang ma
tu san » thu san, tu ban, tu can
tu sai » tu bai, tu cai, tu lai

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sai) OR (tu san)) ky nang xa hoi. thien van pham duc ban ((hanh vai) or (hanh va)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sai) OR (tu san)) ky nang xa hoi. thien van pham duc ban ((hanh vai) OR (hanh va)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sai) OR (tu san)) ky nang xa hoi. thien van pham duc ban ((hanh vai) or (hanh va)) cua tre".
• Adding a wildcard symbol may retrieve word variants: ((tu sai) OR (tu san)) ky nang xa hoi. thien van pham duc ban ((hanh vai) or (hanh va)) cua tre*.
