Perhaps you should try some spelling variations:
thanh trung » thanh tung
phap thuoc » phap thuc, pham thuoc, phap truoc
doi chieu » doi chi, ho chieu, mot chieu
cap thuoc » cay thuoc, cao thuoc, cap nuoc
trong bac » trong cac, trong ban, trong ba
bac thanh » ban thanh, cac thanh, tai thanh
thanh lap » thanh san, phan lap, thanh hai
doc hieu » toc thieu, hoc thieu, hoc hien

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: ((doi chieu) OR (doc hieu)) xanh - thanh trung ((cap thuoc) OR (phap thuoc)) trong bac thanh lap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doi chieu) OR (doc hieu)) xanh - thanh trung ((cap thuoc) or (phap thuoc)) trong bac thanh lap~".
• Adding a wildcard symbol may retrieve word variants: ((doi chieu) OR (doc hieu)) xanh - thanh trung ((cap thuoc) or (phap thuoc)) trong bac thanh lap*.
