vat hanh » vat thanh, va hanh, nhat hanh
van hanh » van thanh, ban hanh, van anh
lanh ly » lanh lay, doanh ly, khanh ly
ly nang » ky nang, ly hang, ly vang
cua tre » cua te, cuu tre, cua triet
ve cau » ke cau, ve cac, le cau
va cau » van cau, va cac, va dau
vi cua » vai cua, di 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: thuat lanh ly nang x hoi. hieu ((ve cau) or (va cau)) thuc ((vat hanh) OR (van hanh)) vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat lanh ly nang x hoi. hieu ((ve cau) OR (va cau)) thuc ((vat hanh) OR (van hanh)) vi cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat lanh ly nang x hoi. hieu ((ve cau) or (va cau)) thuc ((vat hanh) OR (van hanh)) vi cua tre*".
