Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
hoc thieu » toc thieu, hoc hien
trang cua » tranh cua, tang cua, thang cua
trung cua » truong cua, trung tuan, trung cap
thanh lap » thanh san, phan lap, thanh van
thanh hai » thanh phan, thanh hoa, thanh san
cong tan » cong tac, cong san, cong thanh

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: hoc thieu xanh - hanh ((trang cua) OR (trung cua)) trong cong tan ((thanh lap) OR (thanh hai))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - hanh ((trang cua) OR (trung cua)) trong cong tan ((thanh lap) or (thanh hai))~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - hanh ((trang cua) OR (trung cua)) trong cong tan ((thanh lap) or (thanh hai))*.
