Perhaps you should try some spelling variations:
sang tao » hang tai
sang lap » sang ma, sang tai, dan lap
sach ky » sach y, sach ty, sach kem
doan vi » doan va, don vi, doan thi
va doan » va doanh, van doan, va dan
hieu ve » hieu va, hieu van
sac ky » cac ky, sai ky
ve cam » ve cham, ve cac, va cam
xuc va » duc va, tuc va, luc va
vi cua » vai cua, di 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: su ((sach ky) OR (sac ky)) ((sang lap) OR (sang tao)) hai. hieu ve cam xuc va doan vi cua tu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ky) or (sac ky)) ((sang lap) OR (sang tao)) hai. hieu ve cam xuc va doan vi cua tu~".
• Adding a wildcard symbol may retrieve word variants: su ((sach ky) or (sac ky)) ((sang lap) OR (sang tao)) hai. hieu ve cam xuc va doan vi cua tu*.
