Financial infos of taiwanese companies

Are private taiwanese companies obligated to report their financial sheets publically?
Where can i find basic financial informations like revenue, number of employees? Is there any public institution, which collect database. Or private page with subscription.
I need to check out few middle - small companies, They have like 100 to 300 workers.

I’m not sure how useful this is to you, but the business register:

provides information about paid-in capital.
