Our tolerating ability is indeed way beyond our imagination. But not until the very critical moment will we 21 our potential tolerating ability. There was a woman in the countryside who got married at the age of 18 and had to escape with her two daughters and a son wherever she could at the age of 26 due to the Japanese army’s invasion. Many people in the village at that time could not 22 the suffering of being a fugitive（亡命者） and wanted to commit suicide. After she knew about it, she would come to those 23 ,saying, “Don’t do that 24 thing.

My life is so happy now!” She was 33 gradually and could not do the farm work anymore. So she stayed at home and did some sewing work. Nevertheless, the Heaven seemed to show no affection to her who had undergone a 34 life. She got her leg broken 35 when she was nursing her grandson. Due to her old age that posed a great risk to her operation, she did not receive operation and had to lie in bed all day long. Her children all cried heavily, while she merely said, “Why do you cry? I am still living.” 36 she could not rise from bed, she did not complain about anything and anybody. Instead, she sat on the bed and did some sewing work. She had learnt scarves-weaving, crafts-making, etc. All her neighbors spoke 37 of her skills and came to learn from her. She lived until 86.

Therefore, no matter what you are suffering from now, do not merely complain about the 39 of our destiny and maintain low-spirited all the time. There are no such setbacks that we could not overcome. Only those who have no confidence and courage to overcome setbacks will be 40 at last!
