Perhaps you should try some spelling variations:
nhan tien » nhan vien, nhan dien, phan tien
tien cua » trien cua, tiep cua, dien cua
thu sac » thu sach, thu san, thu xac
nang xa » nang x, nang ma, mang xa
lang xa » lang ha, dang xay, lang van
va nhan » van nhan, ca nhan, va phan
suc va » duc va, tuc va, luc va
cua te » cua tu
ve cac » va cac, vien cac
sac ky » cac ky, sai ky
ve cao » va cao, ve bao, ve co

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

• Performing a fuzzy search may retrieve terms with similar spellings: thu sac ky ((nang xa) OR (lang xa)) hoi. hieu ((ve cao) or (ve cac)) suc va nhan tien cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sac ky ((nang xa) OR (lang xa)) hoi. hieu ((ve cao) OR (ve cac)) suc va nhan tien cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sac ky ((nang xa) OR (lang xa)) hoi. hieu ((ve cao) or (ve cac)) suc va nhan tien cua te".
• Adding a wildcard symbol may retrieve word variants: thu sac ky ((nang xa) OR (lang xa)) hoi. hieu ((ve cao) or (ve cac)) suc va nhan tien cua te*.
