Perhaps you should try some spelling variations:
hieu ve » hieu va, hieu van
thuc va » thuc vat, thuc dan, thuc day
te sac » te sach, te cac, te san
sac ky » cac ky, sai ky
ve nam » he nam, va nam, le nam
thu va » thue va, tu va, thu ha
vi cua » vai cua
di cua » dai cua, doi cua, de cua

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sac ky nang x ho. hieu ve nam ((thu va) OR (thuc va)) danh ((vi cua) or (di cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky nang x ho. hieu ve nam ((thu va) OR (thuc va)) danh ((vi cua) OR (di cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang x ho. hieu ve nam ((thu va) OR (thuc va)) danh ((vi cua) or (di cua)) tre*".
