My first impression of Hong Kong was: the houses are ridiculously expensive and incredibly small. A single apartment easily starts at tens of millions of dollars. Suddenly, something dawned on me—top-tier cities like Hong Kong, Shanghai, Shenzhen, and Tokyo offer the most job opportunities. If you're not there to start a business, become a boss, or aspire to a high-level management position, the absurdly high cost of living in these major cities will likely force you out. Ordinary people focus on costs; smart people focus on opportunities.
