Example Input: Question: How long had the largest wrestling promotion in Mexico been in existence when Guerrera first appeared for them? Passage:The combination of Guerrera's in ring skills, natural charisma and unique mask quickly landed him a regular job working for Empresa Mexicana de Lucha Libre (EMLL), Mexico's largest wrestling promotion. On September 25, 1981 Fuerza Guerrera made his first appearance at a major EMLL show as he wrestled and defeated Negro Casas on EMLL's 48th Anniversary show. On November 6, 1983 Guerrera defeated Aguila Venezolana in a tournament final to win the vacant Mexican National Lightweight Championship, the first professional wrestling championships of his career.

On December 3, 1985 Fuerza Guerrera captured the Mexican National Welterweight Championship when he defeated Javier Cruz. Guerrera held the title for approximately 240 days before vacating the title as he left EMLL to work for other wrestling promotions in Mexico. By late 1988 Guerrera had returned to EMLL and captured the NWA World Welterweight Championship on October 4, 1988 when he defeated Solar II and won the highest ranking title in the Welterweight division at the time. Guerrera would go on to make several successful title defenses until he lost to Águila Solitaria on June 2, 1980. Guerrera regained the title three days later and went on to have an 808-day reign that included successful title defenses against Pantera II, Americo Rocca, his trainer Gallo Tapado, Misterioso and Octagón. In 1989 Guerrera also began working part-time in the Tijuana, Baja California based World Wrestling Association promotion, winning the WWA Welterweight Championship twice in 1989 and 1990.
