Observe the words collected by other calligraphers, buy some copybooks and show them to your children at home, so you don't have to worry about writing.
Mi Fei's Plum Blossom Fu, Zhao Mengfu's Danba Monument, Tang Yin's Fallen Flower, Yu Shinan's Lanting Preface (this is a bit difficult).
All good words.
Just keep practicing ~
