In 1994, a tragic and unresolved incident shook the academic community in China - the poisoning of Zhu Ling (朱令）, a talented student at Tsinghua University (中国清华大学）. This case, marked by mystery and a lack of conclusive resolution, has remained in the public consciousness for decades, symbolising a quest for justice and closure that beyond borders.

Today, we turn our attention to Australia. A key figure linked to the Zhu Ling case, Sun Wei, now known as Sun Shiyan (孙释颜), is reportedly residing in the lucky country. This petition is not an allegation but a call for awareness and accountability. It is important to clarify that Sun Wei was never formally charged or convicted in relation to Zhu Ling's poisoning due to insufficient evidence. However, the unresolved nature of this case and her alleged connection to it continues to raise concerns and questions within the community.

Australia, known for its strong commitment to public safety, legal responsibility, and human rights, hosts diverse communities, including immigrants like Sun Wei. This petition seeks to uphold these values by emphasising the importance of vigilance and accountability for all residents, regardless of their status.

We call upon the Australian community and authorities to:

1,Prioritise Vigilance in Immigration Processes: In processing immigration cases, such as those related to marriage, skilled migration, and investment, it's essential not to only rely on standard criminal history checks but also to be reasonably vigilant about potential criminal cases with significant social impact. This approach ensures a more comprehensive understanding of an applicant's background, thereby maintaining the integrity and security of Australia's immigration system. It underscores the importance of balancing thoroughness with reasonableness, ensuring that the process is both effective in identifying potential risks and fair to all applicants. 

2. Utilise Polygraph Tests for Justice: Considering the loss of direct evidence in significant unresolved cases like Zhu Ling’s, we suggest the use of polygraph tests on a voluntary basis. This recommendation is not for the purpose of prosecution, but as a means to bring justice to the local and international community. The use of such tests, conducted responsibly and ethically, could play a pivotal role in uncovering truths and facilitating closure in cases where traditional evidence may no longer be available. This step would be a testament to Australia's innovative approach to justice and its commitment to resolving cases that have left lasting impacts on society.

3, Foster Responsibility and Address Unresolved Cases: We aim to create a culture that actively acknowledges and learns from past incidents and unresolved cases like Zhu Ling’s. This involves enhancing public understanding and involvement through local media and community awareness programs, ensuring transparency with regular public updates on significant cases, and establishing support mechanisms for affected victims and families. These steps are essential for strengthening community safety, upholding legal and ethical integrity, and reinforcing Australia's commitment to justice and the rule of law.
