Li Zhi seems to be afraid of Wu Hou. Why?

I don't know this fear. You have to be cautious.

Wu Zetian is much stronger than Li Zhi in being emperor and in political scheming. Li Zhi has been in poor health, and his wife is capable, so she is gradually asked to help with government affairs. Later, she became an equal "double saint". Although her power is not as good as Li Zhi's, she also holds less than half of the power of the imperial court. Although Wu Zetian is ambitious, she is really good to Li Zhi, and the relationship between husband and wife is good. At least when Li Zhi was alive, she had no intention of usurping the throne, but had a strong desire for power. Later, when his son became emperor, he was incompetent, and Wu Zetian, who was in power, was about to usurp the throne. Li zhi relies more and more on Wu Zetian's ability, and at the same time has husband and wife feelings. Of course, he must be afraid. He is not a fool, but no woman has ever been an emperor, and no one thought of it. Li Zhi actually wanted to keep Wu Zetian for her son, but she didn't expect such an ending.
