cac xuc » cam xuc, cac nuoc, chat xuc
hieu va » lieu va, hieu qua

san ly » van ly, ban ly
xuc va » duc va, tuc va, luc va
di cua » dai cua, doi cua, do cua
de cua » le cua, te cua, dieu cua
tu san » thu san, tu ban, tu can

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

• If you are trying to use Boolean operators, they must be ALL CAPS: tu san ly va ((xay hoi) OR (tay hoi)). hieu va cac xuc va hanh ((di cua) OR (de cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu san ly va ((xay hoi) OR (tay hoi)). hieu va cac xuc va hanh ((di cua) or (de cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: tu san ly va ((xay hoi) OR (tay hoi)). hieu va cac xuc va hanh ((di cua) or (de cua)) tre*.
