Perhaps you should try some spelling variations:
thuat sai » thuat bai, thuat san, thuat cai
van thanh » ban thanh, van tuan
van hanh » ban hanh, van anh, van ban
dua tren » dung tren
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
sai ky » sac ky
va cam » va cham, va cac, va cao
cua te » cua tu

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

• Performing a fuzzy search may retrieve terms with similar spellings: thuat sai ky nang xa hoi. hieu va cam xuc ((van hanh) OR (van thanh)) vai ((dua tren) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sai ky nang xa hoi. hieu va cam xuc ((van hanh) OR (van thanh)) vai ((dua tren) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sai ky nang xa hoi. hieu va cam xuc ((van hanh) OR (van thanh)) vai ((dua tren) or (cua te))".
• Adding a wildcard symbol may retrieve word variants: thuat sai ky nang xa hoi. hieu va cam xuc ((van hanh) OR (van thanh)) vai ((dua tren) or (cua te))*.
