You can't. According to the inquiry of official website of Jilin University, Article 3 of Employment Management evades that candidates who are related to the staff of the department-level unit where the recruitment position is located may not apply for the same department-level unit. Those who are related may not hold positions in the same institution with direct leadership between superiors and subordinates, or hold positions in organizations (personnel), discipline inspection and supervision, auditing and financial work in institutions led by one party, or hold positions in internal institutions (personnel), discipline inspection and supervision, auditing and financial work directly under the same leader. So relatives of Jilin University can't be in the same unit.
