Expand your social circle in Taiwan

Pardon the apparent negativity but the harsh truth about socializing in Taiwan may be boiled down to "friendships in Taiwan are mostly a means to an end" or "a friend in need is a friend indeed" or perhaps "only fair weather friends exist in Taiwan."
I know a 20ish Brit English teacher who bought a Tiffany diamond ring and sent out invitations to mom and relatives in the UK to have his Taiwanese fiancée cancel the wedding at the 11th hour. He doesn't know what happened but you can bet your bottom dollar it's due to his "career prospects" and not owning a US$1 million condo in Taipei.
If a Taiwanese "friend" calls to meet you, the chances are he or she wants something such as to pitch an MLM product and membership.
Non-Mandarin speakers won't know it but this popular TV show in Taipei had a host who runs a pawnshop appraise jewelry and collectibles brought to the program. He exposed how many Taiwanese have been defrauded by "neighborly" jewelry stores who hyped the value of jewelry that had been doctored.
With "friends" like that, who needs enemies?
Not many Taiwanese would admit it, but "friends" ripping off each other on this island is a time-honored tradition.
In fact just check how "friendly" many Taiwanese bosses treat staffers. If only these workers dare to talk openly.

Sure, you can expect some cultural and language issues in Taiwan, but socializing and intergrating into the local community is no different than other countries. Join a club such as Toastmasters. Due to your native speaking abilities, you can become popular easily and being looked up to. You can also join activity groups or sports groups where you can meet like minded individuals. Volunteer to local services especially those which requires a foreign language. Give generously to your community and you will receive much more in return.

Your advice sounds good in theory. I've been to Toastmaster once and found it to be a stage for Taiwanese playing acting public speaking, with a dash of ESL practice thrown in. About as interesting as watching the laundry dry.

So far I've not found volunteer work calling for foreign language skills. I've approached the local ward office and found their attitude perfunctory at best.

Sports clubs, as the name implies, typically charge a fee, which is  unnecessary for a workout.

Take care meanwhile. By the way give I write short articles based on local news usually. If you'd like to be on my mailing list, then give me your email address.
