Ding and Liang's reward for their victory is a place in Sunday's semifinals against Thailand, who beat Iran 4-1 in the afternoon session.
World number 41 Thepchaiya Un-Nooh and Noppon Saengkham have been one of the surprise packages of the World Cup since beating second seeds Scotland in their opening game.
"We'll pay attention to details and try not to make stupid mistakes," said Liang.
In the evening session, it was Zhou Yuelong's turn to get the crowd on its feet as he helped China B grind out a tough win over Belgium.
Belgium's Luca Brecel had been one of the revelations of the group stages, and the 22-year-old smashed in 65 in double-quick time before making the opening frame safe with an excellent long pot.
But Zhou was determined not to be outshone by the Belgian. When his opponent Jeff Jacobs handed him a table full of reds, he duly cleared up with an impressive 98 break to level the match at 1-1.
And after the teams traded four scrappy, tactical frames, it came down to a straight shoot-out between Zhou and Brecel for a place in the semifinals.
With the match well into its fourth hour, Brecel was starting to look a little jaded, and Zhou took full advantage of a loose safety shot to score a 59 break to leave the Belgian needing snookers.
Brecel refused to give up, laying a tricky snooker for the 19-year-old Chinese star. But Zhou was not to be denied, and duly put the frame beyond the Belgian's reach to secure China B a 4-3 victory.
