Perhaps you should try some spelling variations:
thanh ve » hanh ve, thanh va, thanh vien
thu sai » thu hai, thu tai, thu san
duc ban » duc tan, duc van, dua ban
xuc ban » cuc ban, quoc ban, xuat ban
vu cham » va cham, vu kham, tu cham
hieu vu » hieu va, hieu ve, hieu su
lang ha » long ha
tang ma » mang may, tang van
cua tre » cua te, cuu tre, cua triet
sai ky » sac ky
ve cua » le cua, de cua, te cua

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

• Performing a fuzzy search may retrieve terms with similar spellings: thu sai ky ((lang ha) or (tang ma)) noi. hieu vu cham ((xuc ban) OR (duc ban)) thanh ve cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sai ky ((lang ha) OR (tang ma)) noi. hieu vu cham ((xuc ban) OR (duc ban)) thanh ve cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sai ky ((lang ha) or (tang ma)) noi. hieu vu cham ((xuc ban) OR (duc ban)) thanh ve cua tre".
• Adding a wildcard symbol may retrieve word variants: thu sai ky ((lang ha) or (tang ma)) noi. hieu vu cham ((xuc ban) OR (duc ban)) thanh ve cua tre*.
