China's Guangzhou take a three-goal cushion into the second leg against Kashiwa Reysol thanks to their 4-1 win at the Hitachi Kashiwa Stadium on September 25.
However, former Italy boss Lippi wants his side to continue where they left off as they bid to become China's first finalists in 15 years.
The last Chinese side to reach a final was Dalian Wanda, who were runners-up in the 1998 Asian Club Championships, which was the AFC Champions League's predecessor.
Guangzhou, who have been nicknamed "the Manchester United of Asia", have established themselves as favourites to win this year's competition. If they go on to lift the trophy, they will be the first Chinese side to do so in 23 years and the first since Liaoning's victory in 1990.
"We are still on the way to moving on to the next stage," Lippi told fifa.com.
"I'm 64 years old this year and have been in the coaching business for 30 years, and from that experience I can tell you that you never know what will happen next in football, and Reysol have ability and were a tough side to play this time.
"We are still on the way to moving on to the next stage. But we want to win to advance to the next round."
Meanwhile, FC Seoul hold a 2-0 advantage over Iranian side Esteghlal ahead of their return tie in Tehran.
Esteghlal coach Amir Ghalenoei is confident his side will be able to get off the mark at home.
"One of our aims was to score an away goal, we tried a lot but we couldn't score," Ghalenoei said.
"But the conditions in Tehran are completely different and I believe that we can solve that problem.
"It would have been good if we had scored but I think in Tehran we can score two goals. We will attack a lot and we will play to the best of our abilities in the second match."
The winners from the two-leg semi-finals will progress to a two-leg final.
