Perhaps you should try some spelling variations:
dai schulen » drei schulen, den schulen, der schulen
yang guang » yang yang, yan guan, yang liang
guang dai » zhang dai, bang dai, huang di
shang kai » shang hai
tan yang » dan yang, tan ying, tan yong
yang jui » yang judy, yang xi
yang yi » yang xi

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

• Performing a fuzzy search may retrieve terms with similar spellings: tan yang guang dai schulen ((((yang yi) OR (yang jui))) or (yang di)) shang kai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tan yang guang dai schulen ((((yang yi) OR (yang jui))) OR (yang di)) shang kai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tan yang guang dai schulen ((((yang yi) OR (yang jui))) or (yang di)) shang kai ;*".
