Has anyone compared to the Hangsen they were getting?
No. But I'm curious also. From FT:
New Liquid Brand: Hangda
Dear valued customers,
We are pleased to introduce a new liquid brand
Hangda to you.
Hangda liquids are produced by the factory which produced Hangsen liquids. The quality and taste will be the same with Hangsen liquids.
We have already replaced many listings of Hangsen liquids to Hangda liquids on our website. We will only ship Hangda liquids for orders of
these replaced products which placed on 2/24/2016 HK Time. If you feel uncomfortable about this, you may cancel the items from your order.
Please feel free to let us know if you have any questions. Thank you.
Best regards,
