sach ly » sach y, sach ty, sach hay
sach lo » sach dao, sach doi, sach hoi
van cam » van nam, van lam, van cau
va hanh » van hanh, va thanh, va danh
hanh di » hanh vi, hanh de, hang di
xuc va » duc va, tuc va, luc va
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: te ((sach ly) OR (sach lo)) nang x hoi. hieu van cam xuc va hanh di ((cua viet) or (cua vat))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ly) OR (sach lo)) nang x hoi. hieu van cam xuc va hanh di ((cua viet) OR (cua vat)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ly) OR (sach lo)) nang x hoi. hieu van cam xuc va hanh di ((cua viet) or (cua vat))".
• Adding a wildcard symbol may retrieve word variants: te ((sach ly) OR (sach lo)) nang x hoi. hieu van cam xuc va hanh di ((cua viet) or (cua vat))*.
