Perhaps you should try some spelling variations:
xanh tai » hanh tai, anh tai, vanh tai
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
va cham » va chat, va tham
soc van » hoc van, oc van, sac van
xanh di » danh di, vanh dai
cua tre » cua te, cuu tre, cua triet
tu can » tu ban, thu canh

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((tu cac) or (tu can)) ky nang xa hoi. hieu va cham soc van ((xanh di) OR (xanh tai)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu cac) OR (tu can)) ky nang xa hoi. hieu va cham soc van ((xanh di) OR (xanh tai)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu cac) or (tu can)) ky nang xa hoi. hieu va cham soc van ((xanh di) OR (xanh tai)) cua tre*".
