Perhaps you should try some spelling variations:
thong cong » trong cong, tong cong, phong chong
hoc thieu » toc thieu, hoc hien
anh tang » anh bang, anh dang, anh nang
tang cua » mang cua, hang cua, tang luan
dan phan » doan phan, dan chan, van phan
phan cau » phan dau, phan cac, phan tu
doi chi » doi khi

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) OR (doi chi)) xanh - anh tang cua ((thong cong) OR (thong thong)) dan phan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (doi chi)) xanh - anh tang cua ((thong cong) OR (thong thong)) dan phan cau~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (doi chi)) xanh - anh tang cua ((thong cong) OR (thong thong)) dan phan cau*.
