Through consultation with other shareholders, consulting the contract agreement, seeking legal advice, and reporting the withdrawal of shares to relevant departments. 1. Negotiate with other shareholders: you can communicate with other shareholders to explain your concerns and willingness to withdraw shares. Reach an agreement through consultation and find a solution acceptable to both parties.

2. Check the contracts and agreements: carefully check the contracts and agreements signed when you joined the training school to understand the terms and regulations on withdrawal. Determine the rights and obligations according to the contents of the contract.

3. Seek legal advice: If the negotiation fails and there is no clear withdrawal clause in the contract, you can consult a professional lawyer. Lawyers can help assess the situation and provide legal guidance.

4. Report to relevant departments: it is illegal to run a school without a license. You can report the unlicensed school-running behavior of the training school to the local education department and relevant regulatory agencies. This will prompt the relevant departments to investigate and deal with training schools, and also help safeguard their legitimate rights and interests.
