Perspective: How can Hong Kong lift language barrier facing minorities?

In the second half of the 19th century, the Hong Kong government began to bring in labour from other parts of the British empire.
They recruited people from British India, including what is now Pakistan and Bangledesh, as well as Ceylon (now Sri Lanka). They also brought in people from Malaya, mostly of Indian origin. Many of them joined the local constabulary; others were working as house servants, guards and the like.
But unless you find a job that requires little Chinese skills, the prospects are not bright
Quite a few of them acquired British citizenship and they they eventually settled in Britain. But many did not; they were left behind after July 1997. That presented a dilemma for those who had been living in a sort of self-created enclave.
Going back to their native land does not seem like an easy choice. What about staying here without a desire to be integrated into Chinese society? That's not a pretty option either.
For one thing, the local populace does not really care. They are not hostile, but they maintain a kind of "live and let live" attitude where you have to survive on your own.
Certainly, that is not a problem if you have money or speak English well, or manage to climb the social ladder. But what if you are not a person of means? What if you need to keep yourself afloat, just like the rest of us?
To survive, you need knowledge of the Chinese language. This is why, a few weeks ago, the headmistress of a local Islamic high school, voiced her concerns in a newspaper. According to her, minorities cannot get into the Civil Service Bureau because of the language requirement. (She did not mention the private sector.)
