Perhaps you should try some spelling variations:
van hanh » van thanh, ban hanh, van anh
hanh vai » hanh vi, hanh va, hanh tai
dua tren » dung tren
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
cac xuc » cam xuc, cac nuoc, chat xuc
xuc van » duc van, luc van, xuc ban
sac ky » cac ky
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) OR (sac ky)) nang xa hoi. hieu va cac xuc van hanh vai ((dua tren) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat ((sai ky) OR (sac ky)) nang xa hoi. hieu va cac xuc van hanh vai ((dua tren) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat ((sai ky) OR (sac ky)) nang xa hoi. hieu va cac xuc van hanh vai ((dua tren) or (cua te))*".
