Perhaps you should try some spelling variations:
danh nhan » doanh nhan, thanh nhan, benh nhan
van nhan » van phan, van thanh, van khanh
danh dai » danh dau, danh di, danh sai
va danh » va dinh, va dan, va hanh
thuc va » thuc vat, thuc dan, thuc day
thu sac » thu sach, thu san, thu xac
sang ma » tang ma, nang ma, sang tao
nang xa » nang x, lang xa, nang ma
cua tre » cua te, cuu tre, cua triet
sac ky » cac ky, sai ky

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

• Performing a fuzzy search may retrieve terms with similar spellings: thu sac ky ((nang xa) or (sang ma)) hoi. hieu ((van nhan) OR (danh nhan)) thuc va danh dai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sac ky ((nang xa) OR (sang ma)) hoi. hieu ((van nhan) OR (danh nhan)) thuc va danh dai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sac ky ((nang xa) or (sang ma)) hoi. hieu ((van nhan) OR (danh nhan)) thuc va danh dai cua tre*".
