I just bought a cake of Pu 'er tea for 50 yuan, and found rice husk in it, which tastes like rice. Is it bad tea? why

Whether tea is good or not cannot be judged by the presence or absence of rice husk. Nor can it be generalized. Of course, it is not a good thing to have rice husk, but you should know that Pu 'er tea, especially Pu 'er cooked tea, is fermented by pile fermentation. In this process, some particles are sometimes covered on Pu 'er tea to keep it warm. This is conducive to the fermentation of Pu 'er tea, which can't be said to be caused by negligence in production, because the Pu 'er tea industry now buys raw materials from primary agricultural products, resulting in some foreign bodies in it.
