Perhaps you should try some spelling variations:
zheng ming » zhang ming, cheng ming, zheng rong
chen zheng » chen zhen, chen aizheng, cheng zhang
ming wong » ming kong, ming hung, ming qing
wing tan » wing ian, liang tan, hong tan
wong siu » wong shiu, kong siu, wong sau
yuan zi » yuan li, yuan fei, yuan hui
yan zi » yan zhi, ban zi

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 tan ((yan zi) OR (yuan zi)) chen zheng ming wong siu ;~".
• Adding a wildcard symbol may retrieve word variants: wing tan ((yan zi) OR (yuan zi)) chen zheng ming wong siu ;*.
