Perhaps you should try some spelling variations:
van xanh » van anh, van hanh, van manh
tu sach » thu sach, su sach, te sach
xanh di » danh di, vanh dai, xanh tai
ly nang » ky nang, ly hang, ly vang
xuc van » duc van, luc van, vuc van
di cua » dai cua, doi cua, de cua
cua te » cua tu
ve cac » va cac, vien cac
y nang » ky nang, v nang, may nang
ve cai » va cai, ve tai, ve cau

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ((y nang) OR (ly nang)) xa hoi. hieu ((ve cai) or (ve cac)) xuc van xanh di cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((y nang) OR (ly nang)) xa hoi. hieu ((ve cai) OR (ve cac)) xuc van xanh di cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((y nang) OR (ly nang)) xa hoi. hieu ((ve cai) or (ve cac)) xuc van xanh di cua te*".
