Born in Baotou, Inner Mongolia, Liu excelled in basketball and athletics but did not play football until she was 17 years old. Her parents were initially reluctant to let her play what they saw as a masculine sport. In 1994 Liu joined Japanese second tier club Tasaki Perule FC. She helped win promotion in her first season and remained with the club until 1997. At the 2000 WUSA Draft, Liu was selected by Philadelphia Charge in the first round, second overall behind compatriot Sun Wen. In the United States Liu experienced a culture shock; she bought only raw fruit and vegetables from the supermarket as in China she had been in regimented training camps for so long that she never learned to cook. In the 2001 WUSA season 34-year-old veteran Liu was a success, leading the team on goals and points. She was the first woman to win WUSA's Player of the Week in two consecutive weeks, and the first woman to win it three times. Charge coachMark Krikorian said of Liu: "She has been one of the greatest center midfielders in the world". In 2002 Liu was less effective, contributing two goals and two assists for six points in her 20 regular season appearances. She retired at the end of the season.
International career
At the 1991 FIFA Women's World Cup, Liu played the full 80 minutes in all four of China's games. The hosts reached the quarter-finals before losing 1–0 to Sweden. In the first ever FIFA Women's World Cup match, Liu scored twice in China's 4–0 win over eventual finalists Norway on 16 November 1991. In 1996 she won the silver medal with the Chinese team. She played all five matches and scored one goal. At the 1997 AFC Women's Championship Liu scored four goals in China's 10–0 semi-final win over Taiwan and two goals in the 2–0 final win over obdurate North Korea. She was named tournament MVP. Liu was named in the 16-player All-Star team at the 1999 FIFA Women's World Cup. She scored the winning goal in the 2–1 first round win over Sweden and two more in the 5–0 semi-final rout of defending champions Norway, securing China's place in the final, where they lost a controversial penalty shootout to the United States. In 2000, she was a member of the Chinese team which finished fifth in the Olympic women's tournament. She played all three matches. In 2003 Liu took a role as deputy secretary general of the Beijing Football Association. Following the playing retirement of Liu and influential contemporaries like Sun Wen and Zhao Lihong, the Chinese national team went into sharp decline, culminating in an 8–0 defeat by Germany at the 2004 Athens Olympics. In June 2007 Liu was running the only girls' football school in Beijing, when it closed through lack of interest.
