How do I change the candle lighting time for Hong Kong and....

1. I would like to delete the title which is large and not needed since the times are already correct for Havdalah/Shabbat Ends
2. Change Havdalah to be "Shabbat Ends" 
3. And most importantly change the candle lighting time - it is off by 4 minutes from what we use on our printed community Calendar and website
4. If I want changes in what is shown in the script below do i just remove pieces of the code like geo=geoname to kill the title "Shabbat times for Hong Kong, Central and Western, Hong Kong"- what is cfg?. Tried removing geo=geoname - leaving the geonameid - did not remove the title for me.

<script type="text/javascript" charset="utf-8"
src="https://www.hebcal.com/shabbat/?geo=geoname&amp;geonameid=1819729&amp;m=33&amp;cfg=j&amp;tgt=_top">
</script>

5. Am not good with code do not think I will be able to follow the linked suggestions you have had for others - What i really need is your app (if you have one) for outside of the US.

Help - Thank you!!!
