Perhaps you should try some spelling variations:
hanh hai » thanh hai, nhanh hai, hang hai
ban hanh » ban hang
cua tre » cua te, cuu tre, cua triet
ve cham » va cham, ve chat, vu cham
hai cua » thai cua, dai cua, hoi cua
tang xa » trang xa, tang ma, lang xa
duc ban » duc tan, duc van, dua ban
sac ky » cac ky
ve cam » ve cac, va cam, ve cai

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 ((sac ky) OR (sai ky)) tang xa hoi. hieu ((ve cam) OR (ve cham)) duc ban hanh hai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sac ky) or (sai ky)) tang xa hoi. hieu ((ve cam) OR (ve cham)) duc ban hanh hai cua tre~".
• Adding a wildcard symbol may retrieve word variants: su ((sac ky) or (sai ky)) tang xa hoi. hieu ((ve cam) OR (ve cham)) duc ban hanh hai cua tre*.
