My name is Alan, CHENG Holun and my Chinese name is  鄭浩璘. I was born in Hong Kong on July 30, 1972 and became a Christian since 24th Feb 1990.

I have two very lovely ..... parents

and one younger cute sister named Elaine.

Here are my grandma, and my two beloved cousins:

The younger cousin was brought up by my mom (and me!) when he was very young:

After some studies:

I got my B.Sc. in computer science in CUHK in 1994. After I got my M.Phil in 1996 in HKUST, I studied abroad at UIUC in US to get my Ph.D.

These are my Christian fellowship photos in Hong Kong .....

For all these days,

Those were the days　　　Mary Hopkin

Once upon a time there was a tavern
Where we used to raise a glass or two
Remember how we laughed away the hours
Think of all the great things we would do

Those were the days my friend
We thought they'd never end
We'd sing and dance forever and a day
We'd live the life we'd choose
We'd fight and never lose
For we were young and sure to have our way
La la la la la la la la la
Those were the days, oh yes, those were the days

Then the busy years went rushing by us
We lost our starry notions on the way
If by chance I'd see you in the tavern
We'd smile at one another and we'd say...

Just tonight I stood before the tavern
Nothing seemed the way it used to be
In the glass I saw a strange reflection
Was that lonely woman really me?

Through the door there came familiar laughter
I saw your face and heard you call my name
Oh my friend we're older but no wiser
For in our hearts the dreams are still the same....
