Perhaps you should try some spelling variations:
nhung thi » nhung thoi, phung thi, nhung tri
viet gian » viet giao, viec giang, viet tien
van thanh » ban thanh
van tuan » van quan, van ban, anh tuan
que van » quy van, quyet van, quan van
qua van » quan van, qua san, qua va
qua ban » cua ban, qua quan

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

• Performing a fuzzy search may retrieve terms with similar spellings: nhung thi ((que van) or (((qua van) OR (qua ban)))). viet gian trong ((van thanh) or (van tuan))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: nhung thi ((que van) OR (((qua van) OR (qua ban)))). viet gian trong ((van thanh) OR (van tuan)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "nhung thi ((que van) or (((qua van) OR (qua ban)))). viet gian trong ((van thanh) or (van tuan))".
• Adding a wildcard symbol may retrieve word variants: nhung thi ((que van) or (((qua van) OR (qua ban)))). viet gian trong ((van thanh) or (van tuan))*.
