Perhaps you should try some spelling variations:
dau tren » dau tien, dat tren, dau tieng
sach hoa » sach ha, sach hoi, bach hoa
hoa lang » hoa dan, hoa van
cau tren » cu tren, ca tren, cau treo
cham xuc » chat xuc, cham soc, pham duc
xanh di » danh di, vanh dai, xanh tai
va xanh » va danh, va hanh, va anh
tu sach » thu sach, su sach, te sach
hieu ve » hieu va, hieu van
lang xa » lang ha, dang xay, lang van

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

• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach hoa lang xa hoi. hieu ve ((cham xuc) OR (cam xuc)) va xanh di ((cau tren) OR (dau tren))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach hoa lang xa hoi. hieu ve ((cham xuc) or (cam xuc)) va xanh di ((cau tren) OR (dau tren))~".
• Adding a wildcard symbol may retrieve word variants: tu sach hoa lang xa hoi. hieu ve ((cham xuc) or (cam xuc)) va xanh di ((cau tren) OR (dau tren))*.
