Dear Father,
I am fine here. Hope you are also good there. I am writing this letter to you to remind you that since I have promoted to the next class my school fees have increased. The total amount is Seven Thousand Five Hundred Only, including all the charges. As the date of paying fee is near I want you to please pay my school fees on time to avoid the last moment rush. The school has opened its website and accepting fees online. If you do not have time to come to school you can directly pay the fees through online mode.
I don’t know if this will help
Vâng, nó có thể. Tôi sẽ nói với bạn để đi đến trang web này và chỉ cần dịch nó. Tôi hy vọng tôi đã giúp bạn.
