Saturday: Ships from Guangzhou to Hong Kong

Hi,
we want to travel from GZ to Hong Kong on saturday, 1st of September 2018 - is there a ship from GZ to China Hong Kong City Port, Victoria Harbour, Kowloon or Macau Ferry Terminal in Hong Kong? Is it really running daily? On lhsgp.com I cannot find it.
And does it start from Lianhuashan Port or from Nansha Passenger Port? We arrive via Train in GZ.
Thank you so much for any reliable Information.
Felicitas
