Billionaire ____ Mr. Chen is, he still works long hours every day.
A like B as C such
請問A、C錯在哪呢??
要選A的話要如何改呢? 反之，C的畫如何改??
關於此題B是什麼文法?

Billionaire like Mr. Chen, he still works long hours...as [something or someone] is... phrase 片語習語(?)such 是形容詞或代名詞，沒有介係詞功能。或許... Such a billionaire Mr. Chen is 感覺有點怪怪的o.o

as=雖然，是讓步子句(although)的倒裝句。可以查文法書倒裝句那一章的用法。
