During the team's second group stage match, the 18-year-old midfielder - who plays for Tin Shui Wai Pesagus - received a pass from defender Liu Wai-yip. Lali handled the ball well, shot and scored for Hong Kong.
The entire Hong Kong team performed superbly. Their morale was high and they worked tirelessly.
Unfortunately, soon after Lali's goal, a Liaoning forward headed in the equaliser, dashing Hong Kong's hopes of a win.
Goalkeeper Eric Ching Man-chun had no chance, but he saved numerous other dangerous shots on goal.
Hong Kong could not get the winner, even though midfielder So Chun-yin kept creating opportunities in front of the opponents' goal.
"We would like to win our remaining three group stage matches so we can make it to the quarter-finals," Lali said.
"I am most eager to win against Macau. We lost against them at the Interport U21 Championships. It's time for revenge."
Defender Wai-yip regretted not being able to keep the equaliser out. "We celebrated Lali's goal, but soon after that, my spirits were down when they scored against us. They were just lucky [with the goal]," Wai-yip said.
Even back in his hotel room, the 18-year-old kept thinking about the equaliser. He blamed himself for not stopping it.
"To calm down, I told myself I would do better next time. It is important that I don't commit the same mistakes again," he said.
The team's coach, Micky Wong Wai-ki, said the boys gave their all. "They deserved to win today. If they had done so, they would have come a lot closer to securing a place in the quarter-finals," he said. "But I am confident they will continue to do well in upcoming matches and we still have a chance to progress."
Hong Kong will face Henan, Macau and Jilin over the next few days.
