Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
thanh tung » thanh cong
phap thuoc » phap thuc, pham thuoc, phap truoc
doi chieu » doc hieu, doi chi, ho chieu
cap thuoc » cay thuoc, cao thuoc, cap nuoc
cac phan » cac nhan, cao phan, cap phan
phan lap » phan dau

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