Perhaps you should try some spelling variations:
across sectional » cross section, cross sections, across national
using dann » using ann, using data, using dna
dan yang » daun yang, tan yang, wang yang
tan kong » tan hong
ying jin » yang jin, jing ji, yang jie
dann bin » dong bin
across » agross
cross » gross

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: ((dan yang) OR (tan kong)) ying jin ((across sectional) OR (cross sectional)) using dann bin ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dan yang) or (tan kong)) ying jin ((across sectional) OR (cross sectional)) using dann bin ;~".
• Adding a wildcard symbol may retrieve word variants: ((dan yang) or (tan kong)) ying jin ((across sectional) OR (cross sectional)) using dann bin ;*.
