Undoubtedly, the old man is a righteous person and hopes to embody righteousness through actions. But we must remember that, a righteous objective alone is not enough. There is a need for a proper method to deal with the issue. If this old man's practice was supported by the public, then all of us would soon find ourselves on shaky ground morally. Someone might lose his or her job because of spitting on a public occasion and others might lose his or her lover by jumping a red light at crossroads. After all, no one is perfect.

In this case, education is the best option and online exposure of the young woman is not a wise choice at all.

Zhang Ying (Liaocheng Daily): In recent years there have been many disputes about giving up seats on buses and they have triggered concerns and debates on social morality. Even relevant government departments have interfered. Such debates have strongly backed the elderly, the pregnant and others so-called "weak" groups. In Qingdao, east China's Shandong Province, a pregnant woman took photos of the bus she was riding and put them online because no one on the bus offered her a seat. This group tends to regard them as the "righteous" side and sharply criticizes those who refuse to offer them seats.

To offer seats to the elderly on buses is necessary, but the precondition is that one does this out of true willingness. Unfortunately, in real life, people are forced to be "moral," because if they refuse to offer the seat, they always risk being named and shamed.

People tend frequently to make moral judgments about others. Sometimes, seemingly righteous actions hurt others' legitimate rights, even if the original intention is justified. We encourage people to exercise moral self-discipline but at the same time, respect, tolerance, gratitude and understanding are also very important.

Zeng Ying (www.sina.com.cn): Only when good deeds are based on good will are the good deeds meaningful. If one is forced to offer his or her seat to others on bus, he or she will not feel happy for this good deed. Instead, he will feel embarrassed and unhappy. In real life, offering seats to the elderly and the weak is already a common practice. Disputes over refusals to offer seats are, anyway, rare cases.

Of course, not all people have high standards of behavior and offer seats to the elderly. Sometimes, young people do have personal reasons not to offer up their seats.

In Hangzhou's case, it was wrong for the young woman to refuse to offer her seat but, after all, this is only a violation of proper bus etiquette and she must feel very bad because of being surrounded by critical eyes. It's unacceptable to deal with this bus dispute by subjecting the young woman to intense humiliation on the Internet. You can't punish a bad practice with another bad practice.

Liu Kejun (Chinese Business Morning View): For years, it has been widely recognized the young should offer their seats to the elderly, but this case reminds us of a question: Is it that the young have no choice but to offer their seats to the elderly?

Offering up seats concerns one's personal behavioral standards. This lady paid for this bus trip and theoretically, she enjoys the same right as the old man to use this bus. She hurts no one's rights by refusing to give her seats to others. But it's now believed that the young have an obligation to cede their seats. If you offer up a seat it's your obligation and, if you do not, it's morally wrong and you deserve condemnation.

This will easily kindle antagonistic psychology in the young: I pay for the trip and the elderly take the bus free of charge, so why should I offer you the seat? I have not violated any laws.

As the saying goes: It takes two to tango. To solve this kind of moral disputes, we need effort from both sides. On one hand, the young should realize how great it is to do good deeds and on the other hand, the elderly need to learn to say "thanks" to the young. A smile and gratitude will be more effective in encouraging the young to be willing to do good deeds than condemnation. If you don't believe it, just try!
