Learning Diary, completed cryptozombie, 学习笔记，完成了cryptozombie

Hello Steemit friends, so for the past few days I am learning how to build a smart contract using the website https://cryptozombies.io/, it is by far the best learning material out there, not only its a step by step, line by line teaching, it ask you to do something line by line and then check for you if your programming is correct or not, and so you get a lot of hands on experience which is extremely valuable.

大家好，这几天我在学习ethereum的smart contract，有一个网站叫https://cryptozombies.io/ 是个非常好的学习网站，不但每一样东西都教你，还让你手动练习，然后再帮你查答案，一下子就学会很多东西

The course not only is free but is very comprehensive. It got a total of 6 lesson which took me 4 days to complete. My brain hurt a little because the amount of information that need to digest and learn is quite a lot.
