What is straight path?

Wang Lian saw her turn and cross the road, and without much interest, saw her walk to the other side. A man was standing there. Wang Lian started looking at the shops once more. It began to snow again, but he kept sitting there as the snow fell over him. He stayed there till the lights in the shops shut down, one by one. Then, dusting the snow off his clothes, he got up. If he hadn't been moving his legs from time to time, he would not have been able to stand on his feet. It was half past two in the morning. Pushing his hands into his pockets, and flexing his legs, he began to walk home. He knew that Hui Donghai must have searched for him and not finding him around must have gone home too.

''Where did you go off?'' Hui Donghai shouted seeing Wang Lian who walked in

without saying a word.

''I'm asking you something,'' Saad remonstrated. He shut the door behind

him and came after Wang Lian.

''I didn't go anywhere,'' replied Wang Lian, taking off his jacket.
