　　Dear father,

　　Father’s Day is coming. I’d like to say something to you.

　　You always work hard so that I can receive a better education and live a better life. You are strict with me in my study and help me with my homework. When I failed an exam, you encouraged me to be confident and keep trying. When I had trouble in life, you always told me to be brave and smile at life.

　　You have given me so much, not only in my study but also in my life. Thank you for your deep love. Thank you for all that you have done for me. I love you! I hope you will be healthy and happy forever!

　　Happy Father’s Day!

　　Yours,

　　Li Hua
