Liu Zixu was stunned at the words; he had never expected the school's various delays to actually work in his favor.
Once the contract was signed, Old Tang had to start preparing evidence.
The evidence of the right to be informed wasn't that difficult to obtain; the first step was to prove that Liu Zixu was a student at the school.
A student ID and an admission notice would suffice; some schools collect the admission notices upon enrollment, while others let the students keep them as a memento.
Next was proof of payment; the cost of the military training uniform had been listed in the notification materials, so he could just print out the bank transaction history.
The rest was various procedural evidence, such as the school's address, legal representative, contact information, etc., all of which are public information and easily accessible.
So it went until the next day, when the evidence collection was complete.
