lai cua » dai cua, hai cua, lai chau
vai cua » dai cua, hai cua, bai cua

cau duc » cao duc, cau luc, chu duc
hieu ve » hieu va, hieu van
ho nang » thi nang, kha nang, cao nang
lo nang » ly nang, loai nang, cao nang
ve cau » ke cau, va cau, ve cac
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: thuat sach ((lo nang) OR (ho nang)) x hoi. hieu ve cau duc va hanh ((vai cua) or (lai cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sach ((lo nang) OR (ho nang)) x hoi. hieu ve cau duc va hanh ((vai cua) OR (lai cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach ((lo nang) OR (ho nang)) x hoi. hieu ve cau duc va hanh ((vai cua) or (lai cua)) tre*".
