Perhaps you should try some spelling variations:
phap thuoc » phap thuc, pham thuoc, phap truoc
hieu xanh » chieu xanh, hieu manh, hieu nganh
cap thuoc » cao thuoc, cap nuoc, cua thuoc
cay thuoc » cua thuoc, nam thuoc, va thuoc
cac thanh » bac thanh, ban thanh, cuu 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: doc hieu xanh - thanh cong ((((cap thuoc) OR (phap thuoc))) OR (cay thuoc)) trong cac thanh lap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc hieu xanh - thanh cong ((((cap thuoc) OR (phap thuoc))) or (cay thuoc)) trong cac thanh lap~".
• Adding a wildcard symbol may retrieve word variants: doc hieu xanh - thanh cong ((((cap thuoc) OR (phap thuoc))) or (cay thuoc)) trong cac thanh lap*.
