hanh te » hanh ve, hanh de, hanh he
vu sac » vu sach, vu san, va sac
xuc va » duc va, tuc va, luc va
va cam » va cham, va cac, va cao
sac ky » cac ky, sai ky
ve cam » ve cham, ve cac, ve cai
ma hoi » mai hoi, xa hoi, ma hoa

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 ma hoi. hieu ((ve cam) or (va cam)) xuc va ((hanh te) OR (hanh tu)) cua vat~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sac ky nang ma hoi. hieu ((ve cam) OR (va cam)) xuc va ((hanh te) OR (hanh tu)) cua vat*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sac ky nang ma hoi. hieu ((ve cam) or (va cam)) xuc va ((hanh te) OR (hanh tu)) cua vat*".
