Perhaps you should try some spelling variations:
thuc tien » thuc hien
tai thuc » thai thuc, tri thuc, dai thuc
hanh tai » thanh tai, hang tai, han tai
van hanh » van thanh, ban hanh, van anh
xuc van » duc van, luc van, vuc van
tu sach » thu sach, su sach, te sach
ly hang » ly quang
y hang » ty hang, yu hang, _ hang
va hoa » van hoa, va hoc, ma hoa
ve cac » vien cac

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ((y hang) OR (ly hang)) va hoa. hieu ((ve cac) or (va cac)) xuc van hanh tai thuc tien~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((y hang) OR (ly hang)) va hoa. hieu ((ve cac) OR (va cac)) xuc van hanh tai thuc tien.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((y hang) OR (ly hang)) va hoa. hieu ((ve cac) or (va cac)) xuc van hanh tai thuc tien".
• Adding a wildcard symbol may retrieve word variants: tu sach ((y hang) OR (ly hang)) va hoa. hieu ((ve cac) or (va cac)) xuc van hanh tai thuc tien*.
