After completing her undergraduate degree at Peking University in 1954, Zheng worked as a specialist archaeology teaching assistant in the History Department. In 1955, she was exempted from having her status converted to that of a research student. For the next four years, Zheng studied Shang and Zhou Dynasty archaeology under the guidance of Yin Da. She graduated in 1959 and was assigned to the Institute of Archaeology, Chinese Academy of Social Sciences, continuing to study Shang and Zhou archaeology. In 1959, Zheng was the leader of an excavation team working on the site of Wangwan 王湾 near Luoyang and led archaeological fieldwork training for students of Peking University. The publication of the Luoyang excavations was written during the period 1960-1961, however, after the period of economic reforms in the early 1980s, the manuscript was edited by Zhao Zhiquan 赵芝荃 and published in 1989. In the Autumn of 1962, Zheng was assigned leader of an excavation team working at Anyang researching the Yinxu culture. She was joined by 59 Peking University students, whom Zheng taught archaeological field methods to. During this field season, the four period dating framework for Yinxu was established, with the first period calibrated to the period of King Wu Ding using oracle bones. Further excavations were run at Miaopu North between 1963—1964.
Fuhao
During the Cultural Revolution, all planned excavations were suspended and only small-scale excavations in places under construction were permitted. An agricultural competition was held in the Anyang area in the winter of 1975, which involved flattening the land, repairing drains and other tasks. Zheng arrived to discover ancientbuilding materials north of where the drains were being repaired and conducted excavations. A workshop was excavated, including ceramics and jades. At the same time, Zheng and her team conducted surveys of the area north of Xiaotun Village, taking cores from the soil using augering devices known as Luoyang spades. They found ancient architecture and tamped earth, which prevented local work teams from levelling the hill. Zheng believed there was also a tomb beneath the tamped earth, which the majority of her peers disagreed with. In 1976, excavations were conducted on an area approximately 1,000m². They unearthed 46 sets of foundations, 165 ash pits, and 54 burials - the most important of which was the tomb of Wu Ding's consort and general, Fuhao. Fuhao's tomb was extremely well preserved, and, in contrast to other tombs, had not been robbed. There was a huge number of grave goods, including bronzes, jades, precious stones, ivory, as well as a total of 1,928 bone artefacts and more than 7,000 seashells. Bronze artefacts included 468 ritual vessels and weapons. Of the 210 ritual vessels, 190 were engraved with characters and Fuhao's name was on 109 of them. Zheng identified the characters Fuhao as referring to the prominent individual mentioned in the oracle bones of the Wu Ding period as presiding over rituals and leading soldiers into battle.
