Every time I buy from Ching Shin Fu Chuan, I almost always order their signature - Yakult green tea. I personally prefer it unsweetened because the sweetness of the Yakult is already quite enough. I have tried Yakult green tea from other shops, but the signature item from Ching Shin Fu Chuan still suits my taste better, and the quality has remained stable for decades. It feels like all the Ching Shin outlets in Yuanlin maintain a fairly consistent quality.
