Despite the noise of the conversations going on among fellow diners in the fast-food shop in Mongkok, Lee kin-wah rattles on, hardly paying attention to what is being said around him.
For the past two years the tall and forthright pastor has been preoccupied with a special needs group - new immigrants from China constantly increasing in number, albeit not necessarily to much of a welcome here.
Mr Lee's work today is no longer confined to spreading the word of God. He spends his time working for the inter-denominational Mission to New Arrivals which he founded in late 1997. It has contributed to the boom in services for new immigrants - especially those arriving for family reunions - whose numbers increased after the Government expanded the daily quota from 105 to 150 in July, 1995.
It has also put him in a position to understand what mainlanders need to be able to cope with life in Hong Kong and where the Government's policy falls down.
Yet not even a man as close to the subject as Mr Lee expected the prospect of a mass influx that resulted from the Court of Final Appeal ruling in January, nor the lingering right of abode controversy.
Rather than dampening his enthusiasm, the public outcry convinced him of both the urgency and value of his work.
