Stocks - Unknown is displayed when retrieving data from Google Finance

This is the stock codes I am using:

0700:HKG,9988:HKG,HSI:INDEXHANGSENG,HSCEI:INDEXHANGSENG

“Unknown” is displayed when trying to display index.

Hello,

Thank you for your feedback. The reason why unknown is displayed is that the code you entered is the index code of Google Finance’s stocks. We have not yet processed the index code of this platform. We will optimize it in subsequent versions.

You can try to display this information through the Yahoo platform
For example:
Hang Seng Index: ^HSI:^HSI
