te sach » toc sach
xuc gia » duc gia, luc gia, tuc gia
hieu ve » hieu va, hieu van
ty hang » ly hang, ty xang, thi hang
ty nang » ky nang, ty xang, ly nang
ve cam » ve cham, ve cac, va cam
va chu » va che, va cau
va chi » van chi, va che, va cai

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 ((ty nang) or (ty hang)) xa hoi. hieu ve cam xuc gia thanh ((va chu) OR (va chi)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ty nang) OR (ty hang)) xa hoi. hieu ve cam xuc gia thanh ((va chu) OR (va chi)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ty nang) or (ty hang)) xa hoi. hieu ve cam xuc gia thanh ((va chu) OR (va chi)) tre*".
