Zheng Zheng (Chinese: 郑铮; born 11 July 1989 in Jinan) is a Chinese football player who currently plays as a defender for Shandong Luneng in the Chinese Super League.

Zheng Zheng was a graduate of the Shandong Luneng under-19 youth team and would be promoted to the senior team during the 2008 Chinese Super League season where despite not making an appearance for the team would still receive a league title medal from the club. He received his promotion to the senior team in 2010 when he made his debut for them for them as a starting left back against Pohang Steelers in a 0-1 defeat on March 24, 2010. Despite the defeat Zheng would go on to become a vital member of the team and would go on to score his first goal for the club on May 16, 2010 in a league game against Shenzhen Ruby where Shandong won 1-0. Zheng would have such a breakthrough season that he would not only win the league title with Shandong but also personally win the CFA Young Player of the Year award as well to end an extremely successful season.

Zheng He (1371–1433; simplified Chinese: 郑和; traditional Chinese: 鄭和; pinyin: Zhèng Hé), also known as Ma Sanbao (simplified Chinese: 马三宝; traditional Chinese: 馬三寶) and Hajji Mahmud Shamsuddin (Arabic: حاجي محمود شمس الدين‎) was a Hui-Chinese mariner, explorer, diplomat and fleet admiral, who commanded voyages to Southeast Asia, South Asia, the Middle East, East Africa, and the Horn of Africa collectively referred to as the Voyages of Zheng He or Voyages of Cheng Ho from 1405 to 1433.

Zheng, born as Ma He (馬和 / 马和), was the second son of a Muslim family which also had four daughters, from Kunyang, present day Jinning, just south of Kunming near the southwest corner of Lake Dian in Yunnan.

He was the great great great grandson of Sayyid Ajjal Shams al-Din Omar, a Persian who served in the administration of the Mongolian Empire and was appointed governor of Yunnan during the early Yuan Dynasty. Both his grandfather and great-grandfather carried the title of Hajji, which indicates they had made the pilgrimage to Mecca. His great-grandfather was named Bayan and may have been a member of a Mongol garrison in Yunnan.
