Perhaps you should try some spelling variations:
hanh lai » hanh lam, hanh tai, thanh lap
vu sach » vu bach, su sach, vu khach
van hac » van hoc, van ha, van hai
lai cua » dai cua, hai cua, lai chau
va hanh » van hanh, va thanh, va danh
dan cac » dan cach, dang cac, dan ca
y lang » _ lang, tay lang, yen lang
xuc va » duc va, tuc va, luc va
o lang » hoa lang, hoi lang
cua te » cua tu

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

• Performing a fuzzy search may retrieve terms with similar spellings: vu sach ((y lang) OR (o lang)) xa hoi. thien ((dan cac) or (van hac)) xuc va hanh lai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ((y lang) OR (o lang)) xa hoi. thien ((dan cac) OR (van hac)) xuc va hanh lai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ((y lang) OR (o lang)) xa hoi. thien ((dan cac) or (van hac)) xuc va hanh lai cua te".
• Adding a wildcard symbol may retrieve word variants: vu sach ((y lang) OR (o lang)) xa hoi. thien ((dan cac) or (van hac)) xuc va hanh lai cua te*.
