Perhaps you should try some spelling variations:
how slower » low lower
yang phang » yong phang, yang yang, yan zhang
wang yang » wang yan, wang liang, wang yanling
phang der » anhang der, gang der, klang der
der rent » der re, der rede
song min » song ming, gong min, jong min
how slow » how low, grow slow, too slow

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: wang yang phang der rent song min ((how slow) OR (((how slower) OR (has slower)))) ;~.
• Adding a wildcard symbol may retrieve word variants: wang yang phang der rent song min ((how slow) or (((how slower) or (has slower)))) ;*.
