I hope you are all well. I have been in Hong Kong for three days, and I'm having a great time. Yesterday morning. our good friend, Tony, came to my hotel. After breakfast, he showed me 1 the city. It was a very 2 day, but I saw many 3 places. First we visited the Ocean Park. After that we took a taxi to St. John's Cathedral. I think it is a very 4 church. Then we went to Victoria Peak. There we could see all 5 Hong Kong. It was really 6 . After dinner, we caught a bus to a 7 . On the bus back to the 8 , we both felt tired but 9 . Tony didn't leave until 10 at night. We enjoyed ourselves very much. Best wishes. Yours, John |
