Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
wang yang » wang yan, wang liang
tan siew » tham siew, mah siew, man sie
siew pei » siew hai, chew pei, siew ee
pei yang » wei yang, hui yang, pei yun
3 long » a long, 3.2 long, 3.1 long
2 long » a long, 3.2 long, 6.2 long

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((((wang yang) or (wang yanling))) or (yang guang)) tan siew pei yang ((3 long) OR (2 long)) du ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wang yang) OR (wang yanling))) OR (yang guang)) tan siew pei yang ((3 long) OR (2 long)) du ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wang yang) or (wang yanling))) or (yang guang)) tan siew pei yang ((3 long) OR (2 long)) du ;*".
