How to write a thank-you letter for cooking training?

Dear (x) Chef:

Under your careful guidance, we have made great progress, and you have worked hard. Thank you.

During the study of art, you love life as a child and care about us as a father, helping us realize that chefs also serve the people and must have a heart-and-soul attitude. You are more concerned about the growth of our skills. Knife-making, fire fighting ... you are great. You still care about our health. Who gets a mother's greeting when she has a minor illness and pain, and the small stove rice is brought to bed as usual? ...

When we are about to leave, we have to say again, master, thank you very much.

I wish the teachers success in their work and good health.

All students
