Perhaps you should try some spelling variations:
thuat san » thuat toan, thuat song, thuat lanh
hanh vai » hanh vi, hanh va, hanh tai
nang cau » nang cao, hang cau, nang dau
dau tren » dau tien, dat tren, dau tieng
hieu ve » hieu va, hieu van
phuc va » phuc vu, chuc va, thuc vat
thuc va » thuc vat, thuc dan, thuc day
vai dau » va dau, van dau, xvii dau
san ky » sang ky, van ky, dan ky

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

• Performing a fuzzy search may retrieve terms with similar spellings: thuat san ky nang cau hoi. ((hieu ve) or (lieu va)) cau ((phuc va) OR (thuc va)) hanh vai dau tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat san ky nang cau hoi. ((hieu ve) OR (lieu va)) cau ((phuc va) OR (thuc va)) hanh vai dau tren*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat san ky nang cau hoi. ((hieu ve) or (lieu va)) cau ((phuc va) OR (thuc va)) hanh vai dau tren*".
