Input: Article: In a series of emergency meetings that lasted from 2–5 October, Chinese leaders debated whether to send Chinese troops into Korea. There was considerable resistance among many leaders, including senior military leaders, to confronting the U.S. in Korea. Mao strongly supported intervention, and Zhou was one of the few Chinese leaders who firmly supported him. After Lin Biao politely refused Mao's offer to command Chinese forces in Korea (citing his upcoming medical treatment), Mao decided that Peng Dehuai would be the commander of the Chinese forces in Korea after Peng agreed to support Mao's position. Mao then asked Peng to speak in favor of intervention to the rest of the Chinese leaders. After Peng made the case that if U.S. troops conquered Korea and reached the Yalu they might cross it and invade China the Politburo agreed to intervene in Korea. Later, the Chinese claimed that US bombers had violated PRC national airspace on three separate occasions and attacked Chinese targets before China intervened. On 8 October 1950, Mao Zedong redesignated the PLA North East Frontier Force as the Chinese People's Volunteer Army (PVA).

Now answer this question: Who was Lin Biao replaced with when he declined to lead the Chinese troops in Korea?

Output: Peng Dehuai

Input: Article: Jack Brickhouse manned the Cubs radio and especially the TV booth for parts of five decades, the 34-season span from 1948 to 1981. He covered the games with a level of enthusiasm that often seemed unjustified by the team's poor performance on the field for many of those years. His trademark call "Hey Hey!" always followed a home run. That expression is spelled out in large letters vertically on both foul pole screens at Wrigley Field. "Whoo-boy!" and "Wheeee!" and "Oh, brother!" were among his other pet expressions. When he approached retirement age, he personally recommended his successor.

Now answer this question: What was Jack Brickhouse's trademark call?

Output: Hey Hey!
