Before having our presentation, we had identified our topic, which is a sightseeing tour to Hong Kong. We have chosen this topic because we have interests in it.

There is quite a lot of grammatical mistake. You seems to have a weak understanding in using tenses and articles. Pronouns are also hard to be understood.
However, the content is a little bit strange and quite incomprehensible. I just tried my best to make corrections on the grammar with no adjustment in content.
