Perhaps you should try some spelling variations:
thien van » thi van
van pham » san pham, van phan, van phat
hanh tai » thanh tai, hang tai, han tai
hanh vai » hanh vi, hanh va, hanh van
duc ban » duc tan, duc van, dua ban
cua tre » cua te, cuu tre, cua triet
nang xa » nang x, lang xa, nang ma
sang ky » sang kyo, dang ky, tang ky
san ky » van ky, dan ky, ban ky

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

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