Perhaps you should try some spelling variations:
xuyen tai » xuyen tac, nguyen tai, truyen tai
khoe cong » hoc cong, cho cong, khu cong
khoa cong » hoa cong, hoc cong, cho cong
cac khoi » cac thoi, cac khoan, cach thoi
cac thu » cach thuc, cac thoi
ban kem » banh kem, ban ke, hanh kem
kem ly » ke ly
dong » dung

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: xuyen tai ((cac khoi) OR (cac thu)) đe co ban kem ly ((khoe cong) OR (khoa cong)) dong~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "xuyen tai ((cac khoi) or (cac thu)) đe co ban kem ly ((khoe cong) OR (khoa cong)) dong~".
• Adding a wildcard symbol may retrieve word variants: xuyen tai ((cac khoi) or (cac thu)) đe co ban kem ly ((khoe cong) OR (khoa cong)) dong*.
