On April 17, 2020, on the twins' one-month milestone, the Chengdu Research Base announced their names together with the Sichuan medical teams that had worked in Hubei during the COVID-19 outbreak, through a live video link.
- Re Gan Mian (热干面) — Wuhan's signature noodle dish — was given to the elder twin (乳名 Ping Ping / 平平) as a tribute to the anti-epidemic medical teams.
- Dan Hong Gao (蛋烘糕) — a Chengdu street snack — was given to the younger twin (乳名 An An / 安安), pairing the two cities through their best-known foods.
At one month, Re Gan Mian weighed over 1,000 grams and Dan Hong Gao over 800 grams, both in good health. The base presented adoption certificates and custom panda culture gift packages for the twins to the medical teams of Chengdu Medical College Second Affiliated Hospital · CNNC 416 Hospital (成医附二院·核工业四一六医院) and The First Affiliated Hospital of Chengdu Medical College (成都医学院第一附属医院).
