Perhaps you should try some spelling variations:
ly lang » ly hang, ly vang, le lang
hieu ve » hieu va, hieu van
hanh di » hanh vi, hanh de, hang di
cua tre » cua te, cuu tre, cua triet
ha hoi » hoa hoi, ha noi, va hoi
ve cam » ve cham, ve cac, va cam
di cua » dai cua, doi cua, de cua
bach » sach, cach, bac

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: vu bach ly lang ((ha hoi) OR (xa hoi)). hieu ve cam ((duc va) OR (thuc vat)) hanh di cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu bach ly lang ((ha hoi) OR (xa hoi)). hieu ve cam ((duc va) or (thuc vat)) hanh di cua tre~".
• Adding a wildcard symbol may retrieve word variants: vu bach ly lang ((ha hoi) OR (xa hoi)). hieu ve cam ((duc va) or (thuc vat)) hanh di cua tre*.
