cham xuc » cam xuc, chat xuc, pham duc
cua tre » cua te, cuu tre, cua triet
hanh da » hanh dao, hanh dua, hanh va
hieu va » lieu va, hieu qua
sac ky » cac ky
da cua » dai cua, day cua, dan cua
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: tu ((sac ky) OR (sai ky)) nang x hoi. hieu va ((cham xuc) or (cham soc)) ban hanh da cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sac ky) OR (sai ky)) nang x hoi. hieu va ((cham xuc) OR (cham soc)) ban hanh da cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sac ky) OR (sai ky)) nang x hoi. hieu va ((cham xuc) or (cham soc)) ban hanh da cua tre".
• Adding a wildcard symbol may retrieve word variants: tu ((sac ky) OR (sai ky)) nang x hoi. hieu va ((cham xuc) or (cham soc)) ban hanh da cua tre*.
