Perhaps you should try some spelling variations:
cham thuc » nham thuc, pham thuc, tham thuc
cua triet » cua viet, su triet, va triet
vat danh » va danh, van danh, luat danh
lang xa » lang ha, dang xay, lang van
hieu va » lieu va, hieu qua
va cham » va chat, va tham
danh va » doanh va, hanh va, anh va
cuu tre » cau tren, cau treo
cua tre » cua te, dua tren, cua thep
su sac » su sach, su cac, su xac
o lang » hoa lang, hoi lang

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: su sac o lang xa hoi. hieu va cham thuc vat danh va ((((cuu tre) OR (cua tre))) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac o lang xa hoi. hieu va cham thuc vat danh va ((((cuu tre) OR (cua tre))) OR (cua triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac o lang xa hoi. hieu va cham thuc vat danh va ((((cuu tre) OR (cua tre))) or (cua triet))*".
