Perhaps you should try some spelling variations:
zheng ming » zhang ming, cheng ming, zheng rong
chen zheng » chen zhen, chen aizheng, cheng zhang
ming jeong » min jeong, ming kong
jeong shu » jeong su, cong shu
wing yan » wang yan, wing ian, wing tan
yan yi » yang yi, yan zi, yin yi
tan yi » tang yi, tan li, tan ying

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: "wing yan ((yan yi) OR (tan yi)) chen zheng ming jeong shu ;~".
• Adding a wildcard symbol may retrieve word variants: wing yan ((yan yi) OR (tan yi)) chen zheng ming jeong shu ;*.
