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

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 xuc van ((hanh hoi) OR (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 xuc van ((hanh hoi) OR (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 xuc van ((hanh hoi) OR (hanh thoi)) cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sac ((ky sang) or (ky dang)) xa hoi. hieu ve cam xuc van ((hanh hoi) OR (hanh thoi)) cua tre*.
