According to the policy I understand, the accounts of villagers' groups must be recorded and kept for a certain period of time. If there is no data in the accounts of the villagers' group, it is illegal to ask the villagers' representatives to sign it.

According to the provisions of Article 48 of the Villagers' Autonomy Law of People's Republic of China (PRC), villagers' autonomous organizations shall receive, use and manage funds openly, fairly and fairly. At the same time, Article 15 of the Organic Law of Villagers' Committees also stipulates that villagers' groups need to keep accounts and make them public.

Therefore, if there is no data in the accounts of the villagers' group, it is illegal to ask the villagers' representatives to sign it, because it violates relevant laws and regulations. If there is a similar situation, it is suggested to contact the superior villagers' committee and other competent departments to find a solution.
