chua xang » chua nang, chu bang, chua dong
manh toan » thanh toan, anh tuan, tinh toan
tranh va » tranh van, trang va, thanh va
trinh va » trinh van, trinh vat, trinh ve
toan tap » toan ban
chuc » thuc, chu, phuc

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

• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chua xang) OR (chuc nang)) - canh ((tranh va) or (trinh va)) tuong duong manh toan tap~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chua xang) OR (chuc nang)) - canh ((tranh va) OR (trinh va)) tuong duong manh toan tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chua xang) OR (chuc nang)) - canh ((tranh va) or (trinh va)) tuong duong manh toan tap".
• Adding a wildcard symbol may retrieve word variants: ho ((chua xang) OR (chuc nang)) - canh ((tranh va) or (trinh va)) tuong duong manh toan tap*.
