Why is the former residence of Jiang Baili, a military strategist, not open?

The real Jiang Baili's former residence is outside Jiangyuan Lane, Shuiyue Pavilion. The well-preserved former residence of Jiang Baili was demolished, and an antique building was built a few blocks away, insisting that it was the former residence of Jiang Baili. I don't know what this means. Does the former residence of celebrities in the village also form a park? (Jiang's "new home" is opposite his former residence)
