Tong Yao bent down to pick up Niuniu and put her on the pushcart, then started helping He Fang push the cart, "Let's go!"
"Little sister, I don't need your help, I can push it myself." People were pretty honest in this era, they worked without trying to slack off. He Fang felt that since she was being paid, she should work.
Besides, Tong Yao, being so thin, didn't seem strong. Her arm was also recovering from an injury. What if she got hurt?
The pushcart was not heavy. Seeing He Fang's determination, Tong Yao didn't insist on helping. The two quickly reached the school within a few minutes.
With He Fang's assistance, Tong Yao unloaded everything from the cart and switched to a coal-ball to boil black tea. He Fang had nothing else to do at home, so she stayed with Niuniu to watch. If she found any way she could assist, she would lend a helping hand, and see how Tong Yao made this milk tea she spoke of.
