Perhaps you should try some spelling variations:
thuat sai » thuat bai, thuat san, thuat cai
van hanh » van thanh, ban hanh, van anh
hanh tai » thanh tai, hang tai, han tai
dua tren » dung tren
nang xa » nang x, lang xa, nang ma
cac xuc » cac nuoc, chat xuc, cac cuoc
sai ky » sac 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 nang xa hoi. hieu qua ((cac xuc) OR (cam xuc)) van hanh tai ((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 qua ((cac xuc) OR (cam xuc)) van hanh tai ((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 qua ((cac xuc) OR (cam xuc)) van hanh tai ((dua tren) or (cua te))*".
