Two Tangs as one ?

[STSH]

Does anyone know if Dennis Tang () and Dang Chung Kwan (6392) are the same person ?<br><br>The on-screen director Fok in Temptation Summary II (Oriental Harem) bears an incredible resemblance to Dennis. He's not credited, but Dang Chung Kwan is. The same guy also makes an appearance in Sex and Curse, again as Dang Chung Kwan.<br><br>Could they be similar-looking brothers ?<br><br>
