Fuelling of the Long March 5 for launching the Chang'e 5 mission (Y5 = 5^th launch of CZ-5) started in the early evening of 23 November - at around 18:30 h BJT. The launch is scheduled for the very early morning hours on 24 November BJT. ESA reported that they prepare for a launch at 21:35 CET on 23 November, providing support for critical mission phases - during launch and upon return "around" 15 December when preparing for the skip re-entry. 
The launch will make a nice play with figures, since the 5^th flight of the Long March 5 will launch the 5^th Chinese lunar mission. Sounds like 5 is a lucky number. ;-) Much success!
