sanh thi » anh thi, oanh thi, nhanh thi
so sanh » do sanh
tai cuu » tai buu, tai cua, thai cua
xa hanh » xa thanh, xa khanh, va hanh
hieu ve » hieu va, hieu van
nang xa » nang x, lang xa, nang ma

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

• Performing a fuzzy search may retrieve terms with similar spellings: so sanh thi nang xa hoi. hieu ve ((cham tuc) or (nham thuc)) xa hanh ((tai cuu) OR (tai cuc)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sanh thi nang xa hoi. hieu ve ((cham tuc) OR (nham thuc)) xa hanh ((tai cuu) OR (tai cuc)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sanh thi nang xa hoi. hieu ve ((cham tuc) or (nham thuc)) xa hanh ((tai cuu) OR (tai cuc)) tre".
• Adding a wildcard symbol may retrieve word variants: so sanh thi nang xa hoi. hieu ve ((cham tuc) or (nham thuc)) xa hanh ((tai cuu) OR (tai cuc)) tre*.
