Perhaps you should try some spelling variations:
land planning » based planning
dam planning » term planning, from planning, 2 planning
china tan » china top, china two, china taiwan
tan yang » dan yang, tan ying, tan yong
yang min » yang mind, yang jin, tang min
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: ((((land planning) OR (dam planning))) OR (road planning)) can china tan yang min hong tan ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((land planning) OR (dam planning))) or (road planning)) can china tan yang min hong tan ;~".
• Adding a wildcard symbol may retrieve word variants: ((((land planning) OR (dam planning))) or (road planning)) can china tan yang min hong tan ;*.
