Perhaps you should try some spelling variations:
than china » tuan china, han china, wuhan china
yang yang » wang yang
longer do » longer _, longer a, long do
yan guan » gan guan, yan yuan, yang guang
wei yang » pei yang, wei wang, wei yang's
a longer » _ longer, 2 longer, 3 longer
yang a » yang ka, yang _, yang 8

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yang yang) OR (wang yan))) OR (yan guan)) ((than china) OR (can china)) wei yang a longer do ;~".
• Adding a wildcard symbol may retrieve word variants: ((((yang yang) OR (wang yan))) OR (yan guan)) ((than china) OR (can china)) wei yang a longer do ;*.
