Perhaps you should try some spelling variations:
sang lai » sang tai, sang lap, mang lai
hang hai » hoang hai, hang tai, thanh hai
hanh hai » thanh hai, nhanh hai, hanh tai
chat duc » chat xuc, chat doc, chet duoc
hieu su » hieu sau, tieu su, hieu so
lai hoi » dai hoi, lai hoa, lai roi
su chat » su phat, du chat, so chat
can ky » van ky, ban ky, tan ky
dan ky » van ky
cua te » cua tu

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: tu ((can ky) OR (dan ky)) sang lai hoi. hieu su chat duc va ((hanh hai) OR (hang hai)) cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((can ky) or (dan ky)) sang lai hoi. hieu su chat duc va ((hanh hai) OR (hang hai)) cua te~".
• Adding a wildcard symbol may retrieve word variants: tu ((can ky) or (dan ky)) sang lai hoi. hieu su chat duc va ((hanh hai) OR (hang hai)) cua te*.
