Can I only go to Hong Kong with my passport?

I have to go back to Dalian to apply for a pass. We don't agree with the way of "passing through Hong Kong with a third-country visa and a third-country ticket and staying for 7 days". This method was indeed feasible in the past, but recently, the Hong Kong Immigration Bureau has strengthened its management and audit in this regard, and will record such a situation. Because there is no entry and exit seal of a third country when entering the country, it will be suspected of illegal detention. Once blacklisted, it will be troublesome to go to Hong Kong again, and in serious cases, you will be fined. Believe me, I am a tourist from Yingkou. I had three guests at the beginning of the year, but one of them was recorded (two people outside may be lucky). So I suggest you don't look for that trouble. Moreover, the third-country air tickets given to you by the general intermediary or travel agency are generally cancelled or simply fake after the ticket is issued.
