Perhaps you should try some spelling variations:
nhan luc » nang luc
danh vai » danh sai, danh va, doanh van
hieu van » hieu va, thien van, lieu va
nam luc » nang luc, nam thuc, nam duoc
dang xa » dang xay, dang ha, dang va
vai cua » dai cua, hai cua, lai cua
lang xa » lang ha, dang xay, lang van
va danh » va dinh, va dan, va hanh
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
cua te » cua tu

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

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