Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, yang yang
yuan wang » yan wang, yuan kang, yuan chang
know when » know what, know them, know who
ming hong » ming hung, ming kong, among hong
ban know » can know, a know, ban nor
min hong » amin hong, tin hong, min hyoung

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

• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang liang) OR (yuan wang)) ban know when change ((ming hong) OR (min hong)) seo ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang liang) or (yuan wang)) ban know when change ((ming hong) OR (min hong)) seo ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang liang) or (yuan wang)) ban know when change ((ming hong) OR (min hong)) seo ;*.
