Perhaps you should try some spelling variations:
nhung thoi » nhung thi, phung thi, nhung loi
thoi que » thoi quen, thon que, thong que
hoc dung » hoc ung, hoc dan, tac dung
dung uoc » dung quoc, dung hoc, dung coc
que van » qua van, quy van, quyet van
coc mo » hoc mo, toc mo
co mo » co mot, co so, co ma

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( nhung thoi que van. noi dung ((coc mo) OR (co mo)) ) or ( nhung thoi que van. hoc dung uoc mo ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( nhung thoi que van. noi dung ((coc mo) OR (co mo)) ) OR ( nhung thoi que van. hoc dung uoc mo )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( nhung thoi que van. noi dung ((coc mo) OR (co mo)) ) or ( nhung thoi que van. hoc dung uoc mo ))".
• Adding a wildcard symbol may retrieve word variants: (( nhung thoi que van. noi dung ((coc mo) OR (co mo)) ) or ( nhung thoi que van. hoc dung uoc mo ))*.
