Keep conscience clear, then never fear.
问心无愧，永不畏惧。
I find it is very difficult for me to keep conscience clear, I always try to cheat the life.
Therefore, I always fear that one day what I have done will be checked by others.
I can imagine how disappointed they will be.
How to make what I have done stand the test of time?
Just like the process used in products tests, list all the requirements, test if the products can satisfy the requirements item by item.
In the depth of winter, I finally learned that within me there lay an invincible summer.
在寒冷的冬天，我终于知道，我的内心有一个永不凋零的夏天。
Keep an invincible summer in your heart.
Keep the passions and hope that will never fade away in your heart.
Then you will be never lose heart in face of difficulties.
You are in my dreams day and night, and the thoughts seem to never fade away.
