Perhaps you should try some spelling variations:
sang tao » hang tai
sanh ky » hanh ky, sang ky, nganh ky
nang ma » tang ma, nang cao, mang may
sang ma » tang ma, mang may, sang tai
qua cac » cua cac
cac xuc » cam xuc, cac nuoc, chat xuc
xuc cac » xuc tac, tuc cac, xuc cam
dan doi » dan hoi, dan toi, van doi
doi cua » dai cua, hoi cua
cua tu » cua tuc, cua su, cua cu

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: do sanh ky ((nang ma) OR (((sang ma) OR (sang tao)))) hoi. hieu qua cac xuc cac dan doi cua tu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "do sanh ky ((nang ma) or (((sang ma) OR (sang tao)))) hoi. hieu qua cac xuc cac dan doi cua tu~".
• Adding a wildcard symbol may retrieve word variants: do sanh ky ((nang ma) or (((sang ma) OR (sang tao)))) hoi. hieu qua cac xuc cac dan doi cua tu*.
