Perhaps you should try some spelling variations:
nhung tuong » nhung huong, nhung phuong, hung vuong
chieu sang » chieu sach, chieu xanh, nhieu tang
hieu lang » hieu quang, nhieu tang, hieu van
trung cua » truong cua, trung tuan, trung cap
tuong van » truong van, trong van, duong van
van thanh » ban thanh, van tuan
thanh cau » thanh chau, thanh mau, nhanh cau
mang cua » manh cua, dung cua, ban cua

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: hoc ((chieu sang) OR (hieu lang)) - hanh ((trung cua) OR (mang cua)) nhung tuong van thanh cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu sang) OR (hieu lang)) - hanh ((trung cua) or (mang cua)) nhung tuong van thanh cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu sang) OR (hieu lang)) - hanh ((trung cua) or (mang cua)) nhung tuong van thanh cau*.
