Perhaps you should try some spelling variations:
hanh dao » lanh dao, thanh dat, thanh dam
hanh dai » hanh tai, vanh dai, thanh dat
cham xuc » cam xuc, chat xuc, cham soc
cuu tre » cua tre, cau tren, cau treo
xuc van » duc van, luc van, vuc van
va cham » va chat, va tham
hieu va » lieu va, hieu qua
lang ha » long ha
lang xa » dang xay, lang van
sac ky » cac ky, sai ky
tu sac » tu sach, tu cac, tu san

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 ((lang xa) or (lang ha)) hoi. hieu va cham xuc van ((hanh dai) OR (hanh dao)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky ((lang xa) OR (lang ha)) hoi. hieu va cham xuc van ((hanh dai) OR (hanh dao)) cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky ((lang xa) or (lang ha)) hoi. hieu va cham xuc van ((hanh dai) OR (hanh dao)) cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu sac ky ((lang xa) or (lang ha)) hoi. hieu va cham xuc van ((hanh dai) OR (hanh dao)) cuu tre*.
