A Hong Kong bank card that can be used to register with Hong Kong brokers and participate in IPOs, such as the IPO of Mixue in February, which has a maximum profit of 30,000 per order. Even if we sell it right after the opening, the profits are still considerable. We can also participate in US stock IPOs. Additionally, at the right time, we can purchase Hong Kong and US stocks.

Of course, for us in the cryptocurrency circle, the most important thing is that we can realize profits through certain Hong Kong brokers. Moreover, having funds on a Hong Kong card provides a level of isolation, avoiding being wiped out in one go, thus diversifying risk, especially in a bear market where many cryptocurrencies may face issues.

When going to Hong Kong to apply for a card, it is essential to go in person. Some say it can be done without being there, but that requires having over 500,000 yuan deposited in a domestic bank, plus notarization and proof, which is too cumbersome and not recommended. When we are in Hong Kong, it is usually done online without needing to provide asset proof, which is much more convenient.

In the past, when going to Hong Kong, the following materials needed to be prepared in advance.
1. Hong Kong and Macau travel permit (processed at the administrative service center, re-stamped)
2. ID card
3. A domestic bank savings card (only used for real-name authentication, no funds involved)
4. Customs clearance receipt (received upon passing through customs, do not lose it, needed for card application)

In addition to preparing the above materials, there are a few more things to do before going to Hong Kong:
A: Call the mobile customer service (10086) or telecom customer service (10000) to activate the roaming feature for free. You can only receive SMS in Hong Kong (this cannot be done after arriving in Hong Kong, remember).
B: Go to Alipay—More—Mobile Recharge—Data—Scroll to the bottom—Overseas Data—Select China Mobile or China Telecom/China Unicom, depending on your SIM card. It can be activated for 10 yuan; currently, the telecom card cannot be activated, please contact customer service.
C: Before going, download the ZhongAn, Bank of China Hong Kong, and HSBC apps in advance. Remember, do not register beforehand; register once you arrive in Hong Kong.

If you have an Android phone, you can open the corresponding bank's official website (generally recommended to open 2-3 banks; if lucky, you can succeed on the spot), download the installation package, and transfer it to your phone via a data cable for installation.

If you have an Apple phone, you will need a foreign Apple ID, as it is frequently required. It is recommended to purchase one directly from the Taiwan region (or Japan region) for 20 yuan each. When logging in, remember to log in only in the App Store, not in settings.

This way, after arriving in Hong Kong, you can casually find a McDonald's or similar place, connect to Wi-Fi, and start applying for a card. Once we successfully obtain the Hong Kong card, we can register with many Hong Kong brokers, such as Futu, Long Bridge, Tiger, Victory, and OSL Securities. However, do not rush to register; it's generally difficult to obtain account opening rewards when registering alone. If needed, we can form a group to apply together.
