I want to know the answer to the following question:
What grew during the second phase of shoen development?
All the background I'm provided with is that "Whereas the first phase of shōen development in the early Heian period had seen the opening of new lands and the granting of the use of lands to aristocrats and religious institutions, the second phase saw the growth of patrimonial "house governments," as in the old clan system.". Is that enough to answer the question?
Answer: yes
