猫流大大发现一个女神，你能告诉我女神的名字么（名字即是flag）

nvshen.zip

Solution:

Extract the file and we could find a txt which contains a string like base64.Decode it:

import base64
inpt = open("nvshen.txt")
out = open("a.out","w")
u = inpt.read()
v = base64.b64decode(u)
out.write(v)

then we found it is a picture. search by image on google and then we could found the flag :爱新觉罗启星
