You are neither the first nor the last person to have this type of situation. One of my best friends who went with me on our last trip to HK is non-Asian, and he had the time of his life with a girl he met at Neptunes 2. You'd be pretty surprised how far not-so-great English can take them
That being said, your chances of having a GFE with a Chinese girl would likely improve if you just pick up at least a few phrases in Chinese. It'd show you're at least trying, and I'm sure in most cases they appreciate the effort.
