An excellent deck for beginners in Mandarin. I don't claim any credit for it, having found it somewhere online in 2023.
There's a card for every word in the (pre-2021) HSK levels 1–6, and the words are ordered by frequency. Every word has pinyin and simplified and traditional characters. Most cards have native-speaker audio for the headword and example sentence, and many also have a picture.
The deck as a whole is larger than AnkiWeb's 250MB size limit, so I've split it into two parts. If you download and import both, you'll find they combine into a single deck.
Part 1: HSK 1–5
This deck has played a big role in the development of my proficiency in Chinese, and I highly recommend it.
