Child defecating in the airplane aisle

A Weibo post has shown a child relieving himself on West Air flight PN6233 from Zhengzhou to Nantong. Fortunately for the passengers, it took place towards the end of the flight as it was descending into Nantong.
And then just yesterday, another Weibo post showed a child defecating on board Shenzhen Airlines flight ZH9709 from Nanjing to Guangzhou. This one, though, might be worse: after a passenger complained saying both bathrooms were vacant, the parents said the bathrooms were too small anyway so they used the back of the plane because it had more room.
