I wonder which is right.
1 ”made ... in Hong Kong"
or
2 ”fallen ... in Hong Kong"?
or,
3 “made … in Hong Kong … fallen in Hong Kong”?

According to this information,
https://en.wikipedia.org/wiki/Typhoon_Mangkhut
The typhoon “Mangkhut caused flooding, especially in low-lying and coastal areas, and over 47,000 trees were knocked over, blocking several major roads. “

I dont’t konow the fact, but my opinion is in favor of the second interpretation…
Would someone tell me about the fact?

"fallen" should be translated as "倒れた".
If the second interpretation is correct, my translation is "このパズルは台風マングットの激しい風が襲う(during the attack of Typhoon Mangkut)香港で倒れた木を材料にして作られています。".

Thanks for all your speedy replies;)
