Confirmed, legal. By inquiring about the provisions of the Accounting Law of People's Republic of China (PRC), enterprises should recognize income according to the basic principle, that is, after receiving the money. Therefore, it is legal for early education institutions to confirm their income after receiving the money. This is also a common practice in business activities, in line with market rules. Before confirming the income, early education institutions should ensure the authenticity and legality of the money received and avoid receiving illegal money or fraud.
