Credit cards: current situation?

Well, after reading the stories I would like to share my experience.
2003 I applied with Chinatrust the Taipei 101 Credit Card.
To my surprise they gave me at once a Gold Card with credit limit of 150k.
I always paid the whole balance at once, used it mainly for travels.
1 year later I upgraded to Platinum Card, valid until the end of the validity of my ARC.
Also in 2005 I asked for a higher credit limit, which was granted to 200k, 6 months later a limit of 300k. Card was valid till May 2008.
Then in November last year, I didn’t found my credit card, informed them, they issued a new one, valid until 2015.
My house bank, Bank of Overseas, gave me also 2 credit cards, valid till 2010.
Credit limit 100k, which is fine for me, cause these i use it only for private spendings.
2005 I applied from Taishin bank Platinum MC and American Express. Well they gave it to me, credit limit 120k, but gave me “only” Gold Card and American Express.
So I never opened these cards.
To my surprise, I received a few days ago 2 new credit cards from Citibank TW, which took over Bank of Overseas. And both are still Platinum Cards.
After reading so many bad experience about Citi, I thought, when my Bank of Overseas are expired, they won’t issue new cards to me. Seems I was wrong.
But when i wanted to open a 2nd account with them, I got turned down with the reason: Only foreigner who speak fluent chinese are allowed to open a second account. WTF.
Seems every bank makes their own rules.
