Perhaps you should try some spelling variations:
lang van » dang van, tang van, hoang van
hieu vu » hieu va, hieu ve, hieu su
duc van » duc va, duc tan, duc manh
luc van » luoc van, luu van, luc va
vu cham » va cham, vu kham, tu cham
cuu tre » cua tre, cau tren, cau treo
lang xa » lang ha, dang xay
bai ky » ban ky, sai ky, bac ky
vi cuu » vi luu, vinh cuu
te bai » te bao, te tai, te ban

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

• Performing a fuzzy search may retrieve terms with similar spellings: te bai ky ((lang xa) OR (lang van)) hoi. hieu vu cham ((luc van) or (duc van)) hanh vi cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te bai ky ((lang xa) OR (lang van)) hoi. hieu vu cham ((luc van) OR (duc van)) hanh vi cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te bai ky ((lang xa) OR (lang van)) hoi. hieu vu cham ((luc van) or (duc van)) hanh vi cuu tre*".
