xanh di » vanh dai, xanh tai
cua tre » cua te, cuu tre, cua triet
vu sac » vu sach, vu san, va sac
sac ky » cac ky, sai ky
va cam » va cham, va cac, va cao
xuc va » duc va, tuc va, luc va
x hoi » xa hoi, o hoi, 5 hoi

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

• Performing a fuzzy search may retrieve terms with similar spellings: vu sac ky nang ((x hoi) OR (x ho)). hieu va cam xuc va ((danh di) or (xanh di)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sac ky nang ((x hoi) OR (x ho)). hieu va cam xuc va ((danh di) OR (xanh di)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sac ky nang ((x hoi) OR (x ho)). hieu va cam xuc va ((danh di) or (xanh di)) cua tre".
• Adding a wildcard symbol may retrieve word variants: vu sac ky nang ((x hoi) OR (x ho)). hieu va cam xuc va ((danh di) or (xanh di)) cua tre*.
