Lu Ting stated, to track the price of gold, you must first choose a good benchmark. Due to different interest rate levels and difficulties in cross-border capital flows, the benchmarks inside and outside the country are different. "To buy gold internationally, the first thing to beat is the yield of U.S. Treasury bonds. For example, the current 10-year Treasury yield is about 4.2%, and the 30-year is about 4.8%. If the annual increase in gold price is below about 4%, then your investment in gold has failed. This is also why we predict that in the next five years, the price of gold is unlikely to fall, but a continuous sharp rise is unlikely."
