Perhaps you should try some spelling variations:
hanh thoi » hanh thuoc, nhanh thai, hanh noi
thoi cua » hoi cua, thai cua, troi cua
van hanh » van thanh, ban hanh, van anh
cua tre » cua te, cuu tre, cua triet
ky sang » ky nang, ky tang, duy sang
ky dang » ky nang, ky danh
xuc van » duc van, luc van, vuc van
ve cham » va cham, ve chat, vu cham
tu sac » tu sach, tu cac, tu san
ve cam » ve cac, va cam, ve cai

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ((ky sang) or (ky dang)) xa hoi. hieu ((ve cam) OR (ve cham)) xuc van hanh thoi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ((ky sang) OR (ky dang)) xa hoi. hieu ((ve cam) OR (ve cham)) xuc van hanh thoi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ((ky sang) or (ky dang)) xa hoi. hieu ((ve cam) OR (ve cham)) xuc van hanh thoi cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sac ((ky sang) or (ky dang)) xa hoi. hieu ((ve cam) OR (ve cham)) xuc van hanh thoi cua tre*.
