Perhaps you should try some spelling variations:
hoc thieu » toc thieu, hoc hien
thi chieu » thi chien, thi hieu, theo chieu
tang luan » dung luan
trong ban » trong san, trong tan, trong quan
tang cua » mang cua, hang cua, thong cua
ban phan » ban phap, van phan, ban than
phan tap » phan lap, han tap, pha tap

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 (thi chieu)) xanh - hanh ((tang cua) OR (tang luan)) dung trong ban phan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (thi chieu)) xanh - hanh ((tang cua) OR (tang luan)) dung trong ban phan tap~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (thi chieu)) xanh - hanh ((tang cua) OR (tang luan)) dung trong ban phan tap*.
