Hongshan Culture, a Neolithic civilization that emerged around 6,500 years ago in north China, is renowned for its exquisite jade artifacts and sacrificial ritual architectures, but an academic predicament remained where few evidences had been found on life settlements during that period.

Over the past decade, Yu, along with her colleagues, discovered more than 700 archaeological sites, over 600 of which were previously unknown. Their efforts put an end to the academic predicament. One of their discoveries, the Ma'anqiaoshan site, is the largest Neolithic settlement site ever excavated in Liaoning.

Yu was never daunted by steep valleys and gullies during their field surveys. She and her colleagues still keep sorting pottery shards, analyzing data, and reviewing literature at the work station every day. "Mountains and wilderness are harsh, but every artifact found there tells us a story of ages old. We are merely listeners, recorders, and inheritors," said Yu.
