"Dad, I'm back, you can go home," said Wang Yao as he walked into the cottage.
"What is this book about?" asked Wang Fenghua as he pointed at Huangting Jing.
"The book is about Taoism. It helps to increase your inner peace," said Wang Yao.
"I see," said Wang Fenghua. He closed the book and got up.
"It is cold on the hill. Make sure you have a thick cover at night," said Wang Fenghua before he left.
"Sure," said Wang Yao.
"San Xian, you walk with my dad home," Wang Yao pointed at his father to San Xian.
"No need, I'm fine," said Wang Fenghua.
San Xian seemed to understand Wang Yao and still ran out of his dog house to follow Wang Fenghua.
San Xian came back 40 minutes later. Wang Yao called home to make sure his father arrived home safely.
