If you directly enter the mainland market from abroad, you have to collect tariffs, and the price is relatively high.
However, entering Hong Kong from abroad does not need to be taxed or the income is very small, and then people who travel to and from the mainland of Hong Kong are used to smuggle from Hong Kong, or other methods are used to evade customs inspection and enter the mainland, thus avoiding customs duties, so that the price will be lower.
