Comrade Chin seems to find Song rather distasteful in the way that she talks about actors and clearly is disturbed that Song is clothed in female garments. In Scene IV, for example, she says openly to Song that she thinks actors are very strange individuals, and it is suggested that she feels they are all homosexual. Consider the following speech:
Acotrs, I think they're all weirdos. My mother tells me actors are like gamblers or prostitutes or--
It is only Song's swift interruption that prevents her going further. This is something that is referred to later on in the scene when Comrade Chin stridently reminds Song that "there is no homosexuality in China" and then leaves. It is interesting that although these two characters are on the one hand fighting on the same side, on the other hand the text makes it clear that there are massive divisions between them that would suggest that actually, they are just as divided as Song is from Gallimard.
