Here's what the author told Wordsbody:
"Writers Nury Vittachi and Jane Camens asked booklovers in Hong Kong to petition the Immigration Department and went on radio shows to talk about it. Newspaper reporters were brought in and the Nigerian Consulate was contacted to talk to the Immigration Department too, which they did. In fact, I have never felt so much love like this before, since I became a writer.
The Chinese people happen to be sensitive towards the media and protests.
When I went to the Chinese embassy in Delhi, the visa section woman couldn't look up to my face. She only said, 'The Immigration Department has now approved your visa. Come and pick your visa tomorrow and don't ask me more questions'. She is still rude, but I forgive her.
I wish to have a swell time in Hong Kong, because I learnt Moses Isegawa, author of Abyssinian Chronicles would be there too."
