Perhaps you should try some spelling variations:
su triet » su viet, su tien, ve triet
hoang de » hoang _
hoang di » hoang dai, hang di, hoang da
va cham » va chat, va tham
xuc van » duc van, luc van, vuc van
nang xa » nang x, lang xa, nang ma
te sach » toc sach
ve cam » ve cham, ve cac, va cam
y nang » ky nang, ly nang, v nang

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 y nang xa hoi. hieu ((ve cam) or (va cham)) xuc van ((hoang di) OR (hoang de)) su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang xa hoi. hieu ((ve cam) OR (va cham)) xuc van ((hoang di) OR (hoang de)) su triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang xa hoi. hieu ((ve cam) or (va cham)) xuc van ((hoang di) OR (hoang de)) su triet".
• Adding a wildcard symbol may retrieve word variants: te sach y nang xa hoi. hieu ((ve cam) or (va cham)) xuc van ((hoang di) OR (hoang de)) su triet*.
