according to the confucian teachings, if shang has an important interview with the emperor for a job in the chinese government but his mother suddenly falls ill, he should do what ?

He should go to the interview because according to the Confucianism, to maintain the balance and equality of the world is necessary to follow the four human dimensions:

1 - Himself

2 - The Community

3 - Nature

4 - The Sky

As you can see, the love for himself is the first. But also, Shang must  understand two things:

1 - The Emperor is his father (according to the Confucianism, the government is the father and people is his children. There is a hierarchy)

2 - His mother ill is Heaven's will

To maintain the balance, Shang must go.
