Query: Three valuable themes

I met the author at an entrepreneurship conference in San Francisco and found the meeting interesting enough to order the book. I found the book to be a mixture of biography, history, and motivational parables. While the biography was perhaps a bit too long, it provided a stage for discussing three very important issues. The first was the potentially destructive impact of dogmatic national policies (The Chinese Cultural Revolution) on a family at the very personal level. The second theme presented the difficulties inherent in and evolution of the relationship between Asia-born parents and their westernized children. The final theme presented the riskiness of small businesses doing business with big companies in China.
