Is there any way to open Longbridge again?

I turned 18 in October and immediately opened accounts for A-shares, Hong Kong stocks, and US stocks. I've tried them all and paid a lot in "tuition fees." The most successful one for me now is US stocks. I want to open an account with a major brokerage, but it seems none are available right now. I ended up opening one with Chifu, but it's so hard to use... The commission fees are ridiculously high. I'd like to ask you experts if there's still a way to open an account with Longbridge, or any other major brokerages. I'm about to go study in Australia soon, and I'm just preparing to go all-in on US stocks 🙏

I've been investing for a few months. I started with 1 million in A-shares, playing the limit-up game, and got cut in half. I've also experienced a 500% gain in US stocks in ten days, and I've been through a total margin call with a single out-of-the-money option. I can only say that A-shares are still better. US stocks can only make you money; you can't learn any skills. You still need to gain more experience in A-shares 😂$Tesla(TSLA.US)
