Perhaps you should try some spelling variations:
tai nang » tai lang, dai nang, tap nang
van hanh » van thanh, ban hanh, van anh
thi nang » thi cong, ki nang, thi hanh
te sach » toc sach
cac xuc » cam xuc, cac nuoc, chat xuc
va hanh » va thanh, va danh, ban hanh
hieu ve » hieu va, hieu van
ve cac » va cac, vien cac
va qua » va quan, va quy, va quang

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((tai nang) OR (thi nang)) xa hoi. hieu ve cac xuc ((va hanh) or (van hanh)) va qua su~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((tai nang) OR (thi nang)) xa hoi. hieu ve cac xuc ((va hanh) OR (van hanh)) va qua su.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((tai nang) OR (thi nang)) xa hoi. hieu ve cac xuc ((va hanh) or (van hanh)) va qua su".
• Adding a wildcard symbol may retrieve word variants: te sach ((tai nang) OR (thi nang)) xa hoi. hieu ve cac xuc ((va hanh) or (van hanh)) va qua su*.
