Hello Yang, With the previous versions of the API, v201802 and earlier, the Ads were immutable. Using v201806, you will be able to mutate your ads without losing their performance data using AdService <https://developers.google.com/adwords/api/docs/reference/latest/AdService>. For this, you will have to add all the required fields listed here <https://developers.google.com/adwords/api/docs/guides/ad-features#mutating_ads_for_v201806_and_later>. Currently, it is not possible to update only specific elements without the required fields. However, I have shared your concern with the team. Please keep an eye on our blog <http://googleadsdeveloper.blogspot.com/search/label/adwords_api> for any updates or announcements related to this feature.
