In Zheng Qing's memory, a headache has always been a major hassle.
Many childhood memories have blurred. For example, he can't remember what the girl he liked in elementary school looked like, nor can he recall the name of the four-wheel car his uncle gave him for his twelfth birthday. Even the promise he made at junior high graduation was completely forgotten unless he flipped open his diary.
But the feeling of a headache, like the moon lingering in the sky every night, remains so fresh and clear.
He can still vividly recall the 'dong dong' sound when he banged his head against the wall due to a headache in his childhood, and he can also remember that the begonia flower in front of the San You Bookstore had just bloomed five petals when he convulsed and fell for the first time.
All of it is engraved deeply in his memory.
Luckily, he had a mentor.
