Perhaps you should try some spelling variations:
hanh vai » hanh vi, hanh va, hanh tai
ky tang » ky nang, kho tang, ky trong
ky dang » ky nang, ky danh
dan hoi » dan hoc, dai hoi, van hoi
hieu vu » hieu va, hieu ve, hieu su
vu chat » va chat, ve chat, du chat
xuc van » duc van, luc van, vuc van
vai cua » dai cua, hai cua, lai cua
tu san » thu san, tu ban, tu can
cua te » cua tu

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu san ((ky tang) OR (ky dang)) dan hoi. hieu vu chat ((xuc van) or (duc tan)) hanh vai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu san ((ky tang) OR (ky dang)) dan hoi. hieu vu chat ((xuc van) OR (duc tan)) hanh vai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu san ((ky tang) OR (ky dang)) dan hoi. hieu vu chat ((xuc van) or (duc tan)) hanh vai cua te*".
