ve triet » va trien, su triet
su sach » so sach, vu sach
hieu ve » hieu va, hieu van
y nang » ly nang, v nang, may nang
ve cam » ve cham, ve cac, va cam
x hoi » xa hoi, o hoi, x ho
gi ve » gia ve, gi de, gi he

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sach ((y nang) or (ky nang)) x hoi. hieu ve cam xuc ((van ban) or (ban hanh)) gi ve triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((y nang) OR (ky nang)) x hoi. hieu ve cam xuc ((van ban) OR (ban hanh)) gi ve triet.
• Adding a wildcard symbol may retrieve word variants: su sach ((y nang) or (ky nang)) x hoi. hieu ve cam xuc ((van ban) or (ban hanh)) gi ve triet*.
