Perhaps you should try some spelling variations:
how slower » has slower, low lower
yong phang » kong hang, ying chang
wang yong » wang yang, wang hyoung, wang yan
phang der » anhang der, gang der, klang der
song mean » song min
der rent » der re, der rede
how slow » how low, grow slow, too slow

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: "wang yong phang der rent song mean ((how slow) OR (how slower)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong phang der rent song mean ((how slow) OR (how slower)) ;*.
