Perhaps you should try some spelling variations:
mean jeong » min jeong, korean jeong
yang yang » wang yang, wang yan
dong skin » dong bin, dof skin
data mean » data map
how cost » low cost, how costly, low costs
how most » how mass, how mo, how mod
jeong yu » jeong su, hong yu, jeong _

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((((dong sin) or (yang yang))) or (dong skin)) ya ((how cost) OR (how most)) data mean jeong yu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((dong sin) OR (yang yang))) OR (dong skin)) ya ((how cost) OR (how most)) data mean jeong yu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((dong sin) or (yang yang))) or (dong skin)) ya ((how cost) OR (how most)) data mean jeong yu ;*".
