Perhaps you should try some spelling variations:
hanh vai » hanh vi, hanh va, hanh tai
thuc van » thuc vat, thuc dan, thuc va
truc van » truc va, truc ban, truc dan
sach tay » xach tay, sach hay, sach nay
te sach » toc sach
vai cua » dai cua, hai cua, lai cua
hieu ve » hieu va, hieu van
lang xa » dang xay, lang van
lang ha » long ha
cua duc » cua tuc, cua nuoc, cua quoc
ve cam » ve cham, ve cac, va cam

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

• If you are trying to use Boolean operators, they must be ALL CAPS: te sach tay ((lang xa) OR (lang ha)) hoi. hieu ve cam ((truc van) OR (thuc van)) hanh vai cua duc~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach tay ((lang xa) or (lang ha)) hoi. hieu ve cam ((truc van) OR (thuc van)) hanh vai cua duc~".
• Adding a wildcard symbol may retrieve word variants: te sach tay ((lang xa) or (lang ha)) hoi. hieu ve cam ((truc van) OR (thuc van)) hanh vai cua duc*.
