Read the article and select the best answer. Article: It's really a tough job for automakers doing marketing and sales in China, where competition is acute and customers have little loyalty. They have tried a range of tricks in recent years. But there should be a moral bottom line. Unfortunately, a Buick dealership used the tragedy of a two-month-old infant to advertise its cars last week on Weibo - Micro blog. And Hyundai Motor followed suit. On March 4, an SUV was stolen with the infant left inside alone in the northeastern city of Changchun. The news spread widely on Weibo after the baby's father called the local police and radio station for help. The next day it was revealed that the infant was choked to death and buried in snow by the thief. The online community expressed its deeply felt sympathy and condolences. The Buick dealership posted a photo of the baby and two of its cars on its official Weibo account to advertise its GPS system that can locate the stolen car. "A few thoughts on the Changchun stolen car and baby incident: when buying a car it's entirely OK to choose a brand with advanced technology," said the post. Though the post was made before tragic fate of the infant was known, the action generated a storm of outrage on Weibo. Some online commentators said it is "marketing at the cost of lives" and "extremely _ ." Worse was the post on Hyundai's official Weibo account that advertised the anti - theft system on its new SUV Santa Fe, an entry made after the child was known to have died. The action also enraged micro bloggers. Both posts were soon deleted. The Buick dealership made an apology on Weibo to the family of the victim and the public. But screenshots saved by users continued to be posted and the negative impact on both brands persists. The two brands probably didn't expect such a firestorm of fury from the Internet community, but they really made a big mistake sinking below the moral bottom line. They certainly ruined their own brand images. The Chinese have the same proverb as the English language - a little leak will sink a great ship....
